From: Sathya Perla Date: Sun, 29 Jan 2012 20:17:39 +0000 (+0000) Subject: be2net: add descriptions for stat counters reported via ethtool X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d45b9d39a1aed7851948460d29b843ce70eb0a68;p=GitHub%2Fmt8127%2Fandroid_kernel_alcatel_ttab.git be2net: add descriptions for stat counters reported via ethtool Also rename a few counters appropritely and delete 2 counters that are not implemented in HW. vlan_mismatch_drops does not exist in BE3 and is accounted for in address_mismatch_drops. Do the same thing for BE2 and Lancer. Signed-off-by: Sathya Perla Signed-off-by: David S.
