Subject: [PATCH net 5/5] bnxt_en: Reduce default ring sizes.
Date: Wed, 10 Feb 2016 17:33:50 -0500	[thread overview]
Message-ID: <1455143630-30140-6-git-send-email-mchan@broadcom.com> (raw)
In-Reply-To: <1455143630-30140-1-git-send-email-mchan@broadcom.com>

The current default tx ring size of 512 causes an extra page to be
allocated for the tx ring with only 1 entry in it.  Reduce it to
511.  The default rx ring size is also reduced to 511 to use less
memory by default.
