2017-01-24IB/iser: remove unused variable from iser_conn structMax Gurtovoy
max_sectors calculation was fixed in commit: 9c674815d346 ("IB/iser: Fix max_sectors calculation"). Thus, iser_conn variable scsi_max_sectors is not needed anymore.

2017-01-24IB/iser: Fix sg_tablesize calculationMax Gurtovoy
For devices that can register page list that is bigger than USHRT_MAX, we actually take the wrong value for sg_tablesize. E.g: for CX4 max_fast_reg_page_list_len is 65536 (bigger than USHRT_MAX) so we set sg_tablesize to 0 by mistake. Therefore, each IO that is bigger than 4k splitted to "< 4k" chunks that cause performance degredation. Remove wrong sg_tablesize assignment, and use the value that was set during address resolution handler with the needed casting.

2017-01-24IB/srp: fix invalid indirect_sg_entries parameter valueIsrael Rukshin
After setting indirect_sg_entries module_param to huge value (e.g 500,000), srp_alloc_req_data() fails to allocate indirect descriptors for the request ring (kmalloc fails).

{data_,}bittiming_const Until commit 08da7da41ea4 can: provide a separate bittiming_const parameter to bittiming functions it was possible to have devices not providing bittiming_const. This can be used for hardware that only support pre-defined fixed bitrates. Although no mainline driver is using this feature so far. This patch re-introduces this feature for the bitrate and the data bitrate (of CANFD controllers). The driver can specify the {data_,}bittiming_const (if the bittiming parameters should be calculated from the bittiming_const) as before or no {data_,}bittiming_const but implement the do_set_{data,}bittiming callback.

Structure emac_phy is renamed to emac_sgmii to clearly indicate it applies to the internal PHY only.

2017-01-22net: dsa: bcm_sf2: Allow non-IMP ports to have Broadcom tags enabledFlorian Fainelli
Parse the "brcm,use-bcm-hdr" boolean property during ports identification to fill a bitmask of ports that should have Broadcom tags enabled. This is needed in some configurations where per-packet metadata can be exchanged using Broadcom tags between the switch and an on-chip acceleration device.

2017-01-22net: dsa: bcm_sf2: Move code enabling Broadcom tagsFlorian Fainelli
In preparation for enabling Broadcom tags on different ports based on configuration information, dedicate a function that is responsible for enabling Broadcom tags for a given port and update the IMP port setup to call it.

2017-01-22net: dsa: bcm_sf2: Add support for BCM7278 integrated switchFlorian Fainelli
Add support for the integrated switch found on BCM7278: - core_reg_align is set to 1, to force a translation into the target address space which is 8 bytes aligned - an alternate SWITCH_REG layout is provided since registers are largely bit/masks compatible but have different offsets - conditional for all CORE_STS_OVERRIDE_{IMP,GMII_P} since those got moved way out of the traditional register space Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-01-22net: dsa: bcm_sf2: Prepare for different register layoutsFlorian Fainelli
In preparation for supporting a new device with a slightly different register layout, affecting the SWITCH_REG and SWITCH_CORE address spaces, perform a few preparatory steps: - allow matching the compatible string against a data description - convert the SWITCH_REG register accesses into an indirection table - prepare for supporting a SWITCH_CORE register alignment requirement Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

2017-01-22net: dsa: bcm_sf2: Make SF2_IO64_MACRO() utilize 32-bit macroFlorian Fainelli
There is no point inlining the 32-bit direct register read/write part, just infer it from the existing macro. This will make it easier to centralize the address rewriting that we are going to introduce later on. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

2017-01-22amd-xgbe: Check xgbe_init() return codeLendacky, Thomas
The xgbe_init() routine returns a return code indicating success or failure, but the return code is not checked. Add code to xgbe_init() to issue a message when failures are seen and add code to check the xgbe_init() return code. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S.

2017-01-22amd-xgbe: Add a hardware quirk for register definitionsLendacky, Thomas
A newer version of the hardware is using the same PCI ids for the network device but has altered register definitions for determining the window settings for the indirect PCS access. Add support to check for this hardware and if found use the new register values. Signed-off-by: Tom Lendacky <thomas.lendacky@amd.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-01-22net: systemport: Add support for SYSTEMPORT LiteFlorian Fainelli
Add supporf for the SYSTEMPORT Lite Ethernet controller, this piece of hardware is largely based on the full-blown SYSTEMPORT and differs in the following: - no full-blown UniMAC, instead we have the MagicPacket matching from UniMAC at same offset, and a GMII Interface Block (GIB) for the MAC-level stuff, since we are always interfaced to an Ethernet switch which is fully Ethernet compliant shortcuts could be made - 16 transmit queues, whose interrupts are moved into the first Level-2 interrupt controller bank - slight TDMA offset change (a register was inserted after TDMA_STATUS, *sigh*) - 256 RX descriptors (512 words) and 256 TX descriptors (not visible) As a consequence of these two things, update the code paths accordingly to differentiate the full-blown from the light version.
