      stmmac: add the Energy Efficient Ethernet support · d765955d
      由 Giuseppe CAVALLARO 提交于 
      This patch adds the Energy Efficient Ethernet support to the stmmac.

Please see the driver's documentation for further details about this support
in the driver.

Thanks also goes to Rayagond Kokatanur for his first implementation.

Note:
 to clearly manage and expose the lpi interrupt status and eee ethtool
 stats I've had to do some modifications to the driver's design and I
 found really useful to move other parts of the code (e.g. mmc irq stat)
 in the main directly. So this means that some core has been reworked
 to introduce the EEE.

v1: initial patch
v2: fixed some sparse issues (typos)
v3: erroneously sent the v2 renamed as v3
v4:
	o Fixed the return value of the stmmac_eee_init as suggested by D.Miller
	o Totally reviewed the ethtool support for EEE
	o Added a new internal parameter to tune the SW timer for TX LPI.
v5: do not change any eee setting in case of the stmmac_ethtool_op_set_eee fails
    (it has to return -EOPNOTSUPP in that case).

      stmmac: do not use strict_strtoul but kstrtoint · ea2ab871
      由 Giuseppe CAVALLARO 提交于 
      This patch replaces the obsolete strict_strtoul with kstrtoint.

v2: also removed casting on kstrtoul.
v3: use kstrtoint instead of kstrtoul due to all vars are integer.
    thanks to E. Dumazet.

      e1000e: remove use of IP payload checksum · 2e1706f2
      由 Bruce Allan 提交于 
      Currently only used when packet split mode is enabled with jumbo frames,
IP payload checksum (for fragmented UDP packets) is mutually exclusive with
receive hashing offload since the hardware uses the same space in the
receive descriptor for the hardware-provided packet checksum and the RSS
hash, respectively.  Users currently must disable jumbos when receive
hashing offload is enabled, or vice versa, because of this incompatibility.
Since testing has shown that IP payload checksum does not provide any real
benefit, just remove it so that there is no longer a choice between jumbos
or receive hashing offload but not both as done in other Intel GbE drivers
(e.g. e1000, igb).

Also, add a missing check for IP checksum error reported by the hardware;
let the stack verify the checksum when this happens.

      igbvf: fix divide by zero · 0e90b49c
      由 Mitch A Williams 提交于 
      Using ethtool -C ethX rx-usecs 0 crashes with a divide by zero.
Refactor this function to fix this issue and make it more clear
what the intent of each conditional is. Add comment regarding
using a setting of zero.
