Subject: bonding: get rid of IFF_SLAVE_INACTIVE netdev->priv_flag
X-Git-Tag: v2.6.39-rc1~468^2~3
X-Git-Url: https://git.openpandora.org/cgi-bin/gitweb.cgi?p=pandora-kernel.git;a=commitdiff_plain;h=2d7011ca79f1a8792e04d131b8ea21db179ab917

bonding: get rid of IFF_SLAVE_INACTIVE netdev->priv_flag

Since bond-related code was moved from net/core/dev.c into bonding,
IFF_SLAVE_INACTIVE is no longer needed. Replace is with flag "inactive"
stored in slave structure
