Subject: [dpdk-dev] [PATCH 1/7] net/bnxt: fix thor tqm entry allocation
Date: Fri, 30 Aug 2019 16:51:55 -0400 [thread overview]
Message-ID: <20190830205201.26644-2-lance.richardson@broadcom.com> (raw)
In-Reply-To: <20190830205201.26644-1-lance.richardson@broadcom.com>
The current TQM backing store size isn't sufficient to allow 512
transmit rings. Fix by correcting TQM SP queue size calculation.
Fixes: f8168ca0e690 ("net/bnxt: support thor controller")
