Date: Wed, 25 Jul 2012 17:36:19 +0300 From: Or Gerlitz <ogerlitz@...lanox.com> To: davem@...emloft.net Cc: netdev@...r.kernel.org, oren@...lanox.com, Amir Vadai <amirv@...lanox.com>, Ben Hutchings <bhutchings@...arflare.com>, Or Gerlitz <ogerlitz@...lanox.com> Subject: [PATCH RESEND net] net/mlx4_en: Limit the RFS filter IDs to be < RPS_NO_FILTER From: Amir Vadai <amirv@...lanox.com> RFS filter id can't have the special value RPS_NO_FILTER, need to skip it when allocating id's. Also, changed an ifdef into a more elegant IS_DEFINED.
