      bonding: Implement port churn-machine (AD standard 43.4.17). · 14c9551a
      由 Mahesh Bandewar 提交于 
      The Churn Detection machines detect the situation where a port is operable,
but the Actor and Partner have not attached the link to an Aggregator and
brought the link into operation within a bound time period. Under normal
operation of the LACP, agreement between Actor and Partner should be reached
very rapidly. Continued failure to reach agreement can be symptomatic of
device failure.

      bonding: Verify RX LACPDU has proper dest mac-addr · bb54e589
      由 Mahesh Bandewar 提交于 
      The 802.1AX standard states:
"The DA in LACPDUs is the Slow_Protocols_Multicast address."

This patch enforces that and drops LACPDUs with destination MAC
addresses other than Slow_Protocols_Multicast address

Intel Wired LAN Driver Updates 2015-02-23

This series contains updates to e1000e, igbvf, i40e and i40evf.

David adds support for i219 devices to the e1000e driver.

Jeff (me) provides two patches to cleanup igbvf, first cleans up the
whitespace issues found and the second cleans up the usage of msleep(),
min() and max() with usleep_range(), min_t() and max_t() respectively.

Kamil updates the shadow RAM read/write functions by refactoring them
to prepare for future work.

Shannon renames the debugfs command "clear_stats pf" to clear_stats port"
to clarify what the function really does.

Mitch refactors the receive routine, by splitting the receive hot path
code into two, one for packet split and one for single buffer, which
improves receive performance.  Disables NAPI polling sooner when closing
the interface to fix an occasional panic during close which was
caused by the driver trying to delete and clean rings at the same time.
Also refactors reset for i40evf, since a recent change to the shutdown
flow messed up the reset flow.  Since i40evf_down() now holds the
critical section lock, we cannot call it from the reset handler, which
also holds the lock.

Nicholas restricts the virtual channel opcodes should remain consistent
between updates to the opcode enum.

Neerav converts the VSI connection type to use a #define instead of
using a magic number.

Anjali updates the registers file to remove registers no longer available.
Also fixes the EMPR interrupt handling, so that we won't trigger another
EMPR when we receive an EMPR event.

Catherine cleans up the variable an_enable since it was set and never
used.

Greg fixes the netdev op that allows the operator to turn MAC/VLAN
spoof checking on and off so that it includes the flag for VLAN spoof
checking.

v2: Updated patch #10 in the series to use test_and_clear_bit() as
    suggested by Sergei Shtylyov

      bcmgenet_hw_params->bds_cnt and GENET_DEFAULT_BD_CNT are used only in Tx init.
