Subject: fs_enet: Don't call NAPI functions when NAPI is not used.
X-Git-Tag: v2.6.25~33^2~29
X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=9a3c243d7d87f401682247dbeff94067d814c192;p=karo-tx-linux.git

fs_enet: Don't call NAPI functions when NAPI is not used.

fs_enet_close() calls napi_disable() unconditionally. This patch skips the
call when use_napi isn't set.
