Subject: [PATCH 01/11] wil6210: add wil_netif_rx() helper function
Date: Sun,  8 Sep 2019 11:32:45 +0300
Message-ID: <1567931575-27984-2-git-send-email-merez@codeaurora.org> (raw)
In-Reply-To: <1567931575-27984-1-git-send-email-merez@codeaurora.org>

From: Dedy Lansky <dlansky@codeaurora.org>

Move common part of wil_netif_rx_any into new helper function and add
support for non-gro receive using netif_rx_ni.
