2018-03-13mwifiex: fix incorrect ht capability problemGanapathi Bhat
IEEE80211_CHAN_NO_HT40PLUS and IEEE80211_CHAN_NO_HT40PLUS channel flags tell if HT40 operation is allowed on a channel or not. This patch ensures ht_capability information is modified accordingly so that we don't end up creating a HT40 connection when it's not allowed for current regulatory domain.

2018-03-13Revert "mwifiex: fix incorrect ht capability problem"Ganapathi Bhat
This reverts commit bcc920e8f08336cbbdcdba7c4449c27137e6b4b9. Drivers gets hardware info and updates ht_cap field of wiphy->bands during initialization. Once updated during init, ht_cap must not be modified as it reflects the capability supported by hardwawre. Above patch tries to modify the ht_cap field and this results in wrongly advertising capabilities during association.

Lots of the wireless driver vendor Kconfig symol help text says "questions about cards." (2 spaces between "about" and "cards") Besides dropping one of those spaces, it also needs some other word inserted there. Instead of putting each vendor's name there, I chose to say "these" cards in all of the Kconfig help text.

2018-03-13rsi: improve RX packet handling in USB interfacePrameela Rani Garnepudi
Curretly, RX packet processing is done sequencially. To improve the efficiency, RX skb queue is introduced. Here, while preparing RX URB skb is allocated and used for RX buffer. When rx done handler is called, enqueue the skb to rx_q and set the thread event. RX thread is modified to dequeue packets from skb queue and process further.

2018-03-13rsi: improve RX handling in SDIO interfacePrameela Rani Garnepudi
Currently, RX packets are handled in interrupt context in SDIO interface. To improve the efficiency of processing RX packets, RX thread and RX skb queues are introduced. When the packet is read from device, driver prepares skb, add to RX queue and trigger RX thread event. RX thread processes the packets from RX queue.

2018-03-13rsi: handle BT traffic in driverSiva Rebbagondla
BT frames are passed through coex and hal modules to BUS. After firmware is loaded, based on the operating mode CARD READY frame comes for each protocol. When BT card ready is received, BT attach is called. Protocol operations are exchanged between the modules at initialization time. Build flag CONFIG_RSI_COEX is introduced to enable coex support if CONFIG_BT_RSIHCI is enabled. Coex operations are valid if coex mode is greater than 1 only.

2018-03-13rsi: add coex supportPrameela Rani Garnepudi
With BT support, driver has to handle two streams of data (i.e. wlan and BT). Actual coex implementation is in firmware. Coex module just schedule the packets to firmware by taking them from the corresponding paths. Structures for module and protocol operations are introduced for this purpose. Protocol operations structure is global structure which can be shared among different modules. Move initialization of coex and operating mode values to rsi_91x_init().

2018-03-12net: phy: set link state to down when creating the phy_deviceHeiner Kallweit
Currently the link state is initialized to "up" when the phy_device is being created. This is not consistent with the phy state being initialized to PHY_DOWN. Usually this doen't do any harm because the link state is updated once the PHY reaches state PHY_AN. However e.g. if a LAN port isn't used and the PHY remains down this inconsistency remains and calls to functions like phy_print_status() give false results. Therefore change the initialization to link being down. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Reviewed-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

Shannon Nelson provides three fixes to the ipsec portion of ixgbe. Make sure we are using 128-bit authentication, since it is the only size supported for hardware offload. Fixed the transmit trailer length calculation for ipsec by finding the padding value and adding it to the authentication length, then save it off so that we can put it in the transmit descriptor to tell the device where to stop the checksum calculation. Lastly, cleaned up useless and dead code. Tonghao Zhang adds a ethtool stat for receive length errors, since the driver was already collecting this counter. Arnd Bergmann fixed a warning about an used variable by "rephrasing" the code so that the compiler can see the use of the variable in question.

2018-03-12Revert "e1000e: Separate signaling for link check/link up"Benjamin Poirier
This reverts commit 19110cfbb34d4af0cdfe14cd243f3b09dc95b013. This reverts commit 4110e02eb45ea447ec6f5459c9934de0a273fb91. This reverts commit d3604515c9eda464a92e8e67aae82dfe07fe3c98. Commit 19110cfbb34d ("e1000e: Separate signaling for link check/link up") changed what happens to the link status when there is an error which happens after "get_link_status = false" in the copper check_for_link callbacks. Previously, such an error would be ignored and the link considered up. After that commit, any error implies that the link is down. Revert commit 19110cfbb34d ("e1000e: Separate signaling for link check/link up") and its followups. After reverting, the race condition described in the log of commit 19110cfbb34d is reintroduced. It may still be triggered by LSC events but this should keep the link down in case the link is electrically unstable, as discussed. The race may no longer be triggered by RXO events because commit 4aea7a5c5e94 ("e1000e: Avoid receiver overrun interrupt bursts") restored reading icr in the Other handler.

Function lan743x_phy_init assigns pointer 'netdev' but this is never read and hence it can be removed. The return error code handling can also be cleaned up to remove the variable 'ret'. Function lan743x_phy_link_status_change assigns pointer 'phy' twice and this is never read, so it also can be removed. Finally, function lan743x_tx_napi_poll initializes pointer 'adapter' and then re-assigns the same value into this pointer a little later on so this second assignment is redundant and can be also removed.

2018-03-12mlxsw: spectrum: Don't depend on ip_gre and ip6_grePetr Machata
mlxsw_spectrum supports offloading of a tc action mirred egress mirror to a gretap or an ip6gretap netdevice, which necessitates calls to functions defined in ip_gre, ip6_gre and ip6_tunnel modules. Previously this was enabled by introducing a hard dependency of MLXSW_SPECTRUM on NET_IPGRE and IPV6_GRE. However the rest of mlxsw is careful about picking which modules are absolutely required, and therefore the better approach is to make mlxsw_spectrum tolerant of absence of one or both of the GRE flavors. Hence rework the NET_IPGRE and IPV6_GRE dependencies to just guard matching modularity, and hide the corresponding code in spectrum_span.c in an #if IS_ENABLED. Mark mlxsw_sp_span_entry_tunnel_parms_common as maybe unused, to muffle warnings if neither GRE flavor is selected, which seems cleaner than introducing a composite #if.

2018-03-12mlxsw: spectrum: Move mlxsw_sp_span_gretap4_route()Petr Machata
Move the function next to the rest of gretap4 functions. Thus the generic functions shared between gretap4 and gretap6 are in one block at the beginning, followed by a gretap4 block, followed by a gretap6 block.

2018-03-12net: ipv6: Introduce ip6_multipath_hash_policy()Petr Machata
In order to abstract away access to the ipv6.sysctl.multipath_hash_policy variable, which is not available on systems compiled without IPv6 support, introduce a wrapper function ip6_multipath_hash_policy() that falls back to 0 on non-IPv6 systems. Use this wrapper from mlxsw/spectrum_router instead of a direct reference.

2018-03-12liquidio: fix ndo_change_mtu to always return correct status to the callerVeerasenareddy Burru
In a scenario where the command queued to firmware get dropped or times out, MTU change from host will not propagate to firmware. So, it is required for host driver to wait for response from firmware or timeout and then return correct status to caller of ndo_change_mtu. Also moved the common code for MTU change from PF and VF driver files to common file lio_core.c Signed-off-by: Veerasenareddy Burru <veerasenareddy.burru@cavium.com> Signed-off-by: Felix Manlunas <felix.manlunas@cavium.com> Signed-off-by: David S.
