From: Ajit Khaparde Date: Fri, 30 Aug 2013 20:01:16 +0000 (-0500) Subject: be2net: set and query VEB/VEPA mode of the PF interface X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=a77dcb8c8ff0b3d65bb3c90f71eabad37e89bc73;p=linux-beck.git be2net: set and query VEB/VEPA mode of the PF interface SkyHawk-R can support VEB or VEPA mode. This patch will allow the user to set/query this switch setting. Signed-off-by: Ajit Khaparde Signed-off-by: David S.
