Subject: [dpdk-dev] [PATCH v2 07/10] sched: cleanup defined constants
Date: Fri, 13 Nov 2015 09:58:33 -0800 [thread overview]
Message-ID: <1447437516-19152-8-git-send-email-stephen@networkplumber.org> (raw)
In-Reply-To: <1447437516-19152-1-git-send-email-stephen@networkplumber.org>
From: Stephen Hemminger <shemming@brocade.com>
Only use RTE_SCHED_PORT_N_GRINDERS from config.
Use RTE_BUILD_BUG_ON for errors.
The remaining implementation constants can be put together.
Signed-off-by: Stephen Hemminger <stephen@networkplumber.org>
