From e52ac3398c3d772d372b9b62ab408fd5eec96840 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Mon, 16 Jan 2012 12:38:59 +0000 Subject: [PATCH] net: Use device model to get driver name in skb_gso_segment() ethtool operations generally require the caller to hold RTNL and are not safe to call in atomic context. The device model provides this information for most devices; we'll only lose it for some old ISA drivers. Signed-off-by: Ben Hutchings Acked-by: Herbert Xu Signed-off-by: David S.
