Subject: [dpdk-dev] [PATCH v4 3/8] net/bnxt: compute and store scattered Rx status
Date: Wed, 29 May 2019 11:02:29 -0400
Message-ID: <20190529150234.15166-4-lance.richardson@broadcom.com> (raw)
In-Reply-To: <20190529150234.15166-1-lance.richardson@broadcom.com>

In preparation for a bnxt vector-mode driver, compute and store
scattered_rx status for the device when started.

v4:
* Moved a fix to bnxt_scattered_rx(), which is introduced in this patch,
  from patch 4 into this patch. (The original version incorrectly
  accounted for a possible QinQ header which was in fact already
  accounted for).
