      b44: Initialize 64-bit stats seqcount · e43c9f23
      由 Florian Fainelli 提交于 
      On 32-bit hosts and with CONFIG_DEBUG_LOCK_ALLOC we should be seeing a
lockdep splat indicating this seqcount is not correctly initialized, fix
that.

      vxlan: fix remcsum when GRO on and CHECKSUM_PARTIAL boundary is outer UDP · be73b304
      由 K. Den 提交于 
      In the case that GRO is turned on and the original received packet is
CHECKSUM_PARTIAL, if the outer UDP header is exactly at the last
csum-unnecessary point, which for instance could occur if the packet
comes from another Linux guest on the same Linux host, we have to do
either remcsum_adjust or set up CHECKSUM_PARTIAL again with its
csum_start properly reset considering RCO.

However, since b7fe10e5("gro: Fix remcsum offload to deal with frags
in GRO") that barrier in such case could be skipped if GRO turned on,
hence we pass over it and the inner L4 validation mistakenly reckons
it as a bad csum.

This patch makes remcsum_offload being reset at the same time of GRO
remcsum cleanup, so as to make it work in such case as before.

      net: ethernet: ti: cpts: fix fifo read in cpts_find_ts · a93439cc
      由 Grygorii Strashko 提交于 
      Now the call chain
 cpts_find_ts()
  |- cpts_fifo_read(cpts, CPTS_EV_PUSH)

will stop reading CPTS FIFO if PUSH event is found. But this is not
expected and CPTS FIFI should be completely drained here. This is most
probably copy-paste error and it has no negative impact as CPTS_EV_PUSH
should not be present in FIFO without TS_PUSH request and
cpts_systim_read() and cpts_find_ts() synchronized by spin_lock.

Correct above by calling cpts_fifo_read() with -1 parameter, so it will
read all CPTS event from FIFO.

      net: ethernet: ti: cpts: fix tx timestamping timeout · 0d5f54fe
      由 Grygorii Strashko 提交于 
      With the low speed Ethernet connection CPDMA notification about packet
processing can be received before CPTS TX timestamp event, which is set
when packet actually left CPSW while cpdma notification is sent when packet
pushed in CPSW fifo.  As result, when connection is slow and CPU is fast
enough TX timestamping is not working properly.

Fix it, by introducing TX SKB queue to store PTP SKBs for which Ethernet
Transmit Event hasn't been received yet and then re-check this queue
with new Ethernet Transmit Events by scheduling CPTS overflow
work more often (every 1 jiffies) until TX SKB queue is not empty.

Side effect of this change is:
 - User space tools require to take into account possible delay in TX
timestamp processing (for example ptp4l works with tx_timestamp_timeout=400
under net traffic and tx_timestamp_timeout=25 in idle).

      net: ethernet: ti: cpts: convert to use ptp auxiliary worker · 999f1292
      由 Grygorii Strashko 提交于 
      There could be significant delay in CPTS work schedule under high system
load and on -RT which could cause CPTS misbehavior due to internal counter
overflow. Usage of own kthread_worker allows to avoid such kind of issues
and makes it possible to tune priority of CPTS kthread_worker thread on -RT
(thread name "cpts").

Hence, the CPTS driver is converted to use PTP auxiliary worker as PHC
subsystem implements such functionality in a generic way now.

      net: phy: rework Kconfig settings for MDIO_BUS · 4c3464a8
      由 Arnd Bergmann 提交于 
      I still see build errors in randconfig builds and have had this
patch for a while to locally work around it:

drivers/built-in.o: In function `xgene_mdio_probe':
mux-core.c:(.text+0x352154): undefined reference to `of_mdiobus_register'
mux-core.c:(.text+0x352168): undefined reference to `mdiobus_free'
mux-core.c:(.text+0x3521c0): undefined reference to `mdiobus_alloc_size'

The idea is that CONFIG_MDIO_BUS now reflects whether the mdio_bus
code is built-in or a module, and other drivers that use the core
code can simply depend on that, instead of having a complex
dependency line.
