This commit removed calls to rtl_set_rx_mode(). This is ok for the
standard path if the link is brought up, however it breaks system
resume from suspend. Link comes up but no network traffic.
Meanwhile common code from rtl_hw_start_8169/8101/8168() was moved
to rtl_hw_start(), therefore re-add the call to rtl_set_rx_mode()
there.
Due to adding this call we have to move definition of rtl_hw_start()
after definition of rtl_set_rx_mode().

each lookup iteration, to identify different packet attributes such as
DSA / VLAN tag, protocol infos, etc. This is used in further

Code logic is similar with arithmetic right shift by constant, and NFP
get indirect shift amount through source A operand of PREV_ALU.
It is possible to fall back to logic right shift if the MSB is known to be
zero from range info, however there is no benefit to do this given logic
indirect right shift use the same number and cycle of instruction sequence.
Suppose the MSB of regX is the bit we want to replicate to fill in all the
vacant positions, and regY contains the shift amount, then we could use
single instruction to set up both.
[alu, --, regY, OR, regX]

NOTE: the PREV_ALU result doesn't need to write to any destination

For indirect shifts, shift amount is not specified as constant, NFP needs
to get the shift amount through the low 5 bits of source A operand in
PREV_ALU, therefore extra instructions are needed compared with shifts by
constants.
Because NFP is 32-bit, so we are using register pair for 64-bit shifts and
therefore would need different instruction sequences depending on whether
shift amount is less than 32 or not.
NFP branch-on-bit-test instruction emitter is added by this patch and is
used for efficient runtime check on shift amount. We'd think the shift
amount is less than 32 if bit 5 is clear and greater or equal than 32
otherwise. Shift amount is greater than or equal to 64 will result in
undefined behavior.
This patch also use range info to avoid generating unnecessary runtime code
if we are certain shift amount is less than 32 or not.

mlx5e-updates-2018-05-17
From: Or Gerlitz <ogerlitz@mellanox.com>
This series addresses a regression introduced by the
shared block TC changes [1]. Currently, for VF->VF and uplink->VF rules, the
TC core (cls_api) attempts to offload the same flow multiple times into
the driver, as a side effect of the mlx5 registration to the egdev callback.
We use the flow cookie to ignore attempts to add such flows, we can't
reject them (return error), b/c this will fail the offload attempt, so we
ignore that.
The last patch of the series deals with exposing HW stats counters through
ethtool for the vport reps.
Dave - the regression that we are addressing was introduced in 4.15 [1] and applies
to nfp and mlx5. Jiri suggested to push driver side fixes to net-next, this is
already done for nfp [2][3]. Once this is upstream, we will submit a small/point
single patch fix for the TC core code which can serve for net and stable, but not
carried into net-next, b/c it might limit some future use-cases.

When merged e-switch is supported, the per-port e-switch is logically

This model allows to offload TC eswitch rules between VFs belonging

Currently, each representor netdev use their own hash table to keep
the mapping from TC flow (f->cookie) to the driver offloaded instance.
The table is the one which originally was added for offloading TC NIC
(not eswitch) rules.
This scheme breaks when the core TC code calls us to add the same flow
twice, (e.g under egdev use case) since we don't spot that and offload
a 2nd flow into the HW with the wrong source vport.
As a pre-step to solve that, we move to use a single table which keeps
all offloaded TC eswitch flows. The table is located at the eswitch
uplink representor object.

This patch makes use of build_skb() throughout in driver's receieve
data path [HW gro flow and non HW gro flow]. With this, driver can
build skb directly from the page segments which are already mapped
to the hardware instead of allocating new SKB via netdev_alloc_skb()
and memcpy the data which is quite costly.
This really improves performance (keeping same or slight gain in rx
throughput) in terms of CPU utilization which is significantly reduced
[almost half] in non HW gro flow where for every incoming MTU sized
packet driver had to allocate skb, memcpy headers etc. Additionally
in that flow, it also gets rid of bunch of additional overheads
[eth_get_headlen() etc.] to split headers and data in the skb.
Tested with:
system: 2 sockets, 4 cores per socket, hyperthreading, 2x4x2=16 cores
iperf [server]: iperf -s
iperf [client]: iperf -c <server_ip> -t 500 -i 10 -P 32

====================
10GbE Intel Wired LAN Driver Updates 2018-05-17
This series contains updates to ixgbe, ixgbevf and ice drivers.
Cathy Zhou resolves sparse warnings by using the force attribute.
Mauro S M Rodrigues fixes a bug where IRQs were not freed if a PCI error
recovery system opts to remove the device which causes
ixgbe_io_error_detected() to return PCI_ERS_RESULT_DISCONNECT before
calling ixgbe_close_suspend() which results in IRQs not freed and
crashing when the remove handler calls pci_disable_device(). Resolved
this by calling ixgbe_close_suspend() before evaluating the PCI channel
state.
Pavel Tatashin releases the rtnl_lock during the call to
ixgbe_close_suspend() to allow scaling if device_shutdown() is
multi-threaded.
Emil modifies ixgbe to not validate the MAC address during a reset,
unless the MAC was set on the host so that the VF will get a new MAC
address every time it reloads. Also updates ixgbevf to set
hw->mac.perm_addr in order to retain the custom MAC on a reset.
Anirudh updates the ice NVM read/erase/update AQ commands to align with
the latest specification.

Don't store repr pointer to reprs array until the representor is
successfully created. This avoids message about "representor
destruction" even when it was never created. Also it cleans-up the flow.
Also, check return value after port alloc.
