From: Yuval Mintz Date: Mon, 4 May 2015 09:34:12 +0000 (+0300) Subject: bnx2x: Fix to prevent inner-reload X-Git-Tag: v4.1~145^2~33 X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=0650c0b8d9efe5b1205116a2febcb984c6c98472;p=platform%2Fkernel%2Flinux-amlogic.git bnx2x: Fix to prevent inner-reload Submit 909d9faae2a44 ("bnx2x: Prevent inner-reload while VFs exist") contained a bug - MTU change was not prevented by it; Instead, it `randomally' prevented bnx2x_resume() from running [harmless yet wrong]. This moves the check to its correct spot. Signed-off-by: Yuval Mintz Signed-off-by: David S.
