From 1b437b977552fa5e491b5faaf390f4ed9baeb2cc Mon Sep 17 00:00:00 2001 From: Chas Williams <3chas3@gmail.com> Date: Tue, 11 Oct 2016 19:04:57 -0400 Subject: [PATCH] net/bnx2x: replace macro with static function Replace BNX2X_TLV_APPEND() with the clearer and safer bnx2x_add_tlv(). bnx2x_add_tlv() was previously prototyped at some point but can be static.
