Subject: [dpdk-dev] [PATCH 16/38] net/sfc/base: make max number of TxQ bufs EF10-specific
Date: Thu, 7 Feb 2019 16:29:21 +0000 [thread overview]
Message-ID: <1549556983-10896-17-git-send-email-arybchenko@solarflare.com> (raw)
In-Reply-To: <1549556983-10896-1-git-send-email-arybchenko@solarflare.com>
From: Igor Romanov <igor.romanov@oktetlabs.ru>
The define EFX_TXQ_MAX_BUFS is used only by EF10 family implementation.
Since the macro is not used by any drivers, it does not require
exposed libefx interface.
Make the define EF10-specific.
