Subject: [dpdk-dev] [PATCH 2/5] ixgbe: make register maps const
Date: Fri,  6 Mar 2015 18:23:21 -0800
Message-ID: <1425695004-29605-3-git-send-email-stephen@networkplumber.org> (raw)
In-Reply-To: <1425695004-29605-1-git-send-email-stephen@networkplumber.org>

These are const data structures, just put them in txt segment
rather than having compiler emit code to set them up on the stack.
