Subject: [PATCH 04/16] wil6210: make sure Rx ring sizes are correlated
Date: Wed, 31 Oct 2018 10:52:12 +0200 [thread overview]
Message-ID: <1540975944-30576-5-git-send-email-merez@codeaurora.org> (raw)
In-Reply-To: <1540975944-30576-1-git-send-email-merez@codeaurora.org>
From: Dedy Lansky <dlansky@codeaurora.org>
When enlarging rx_ring_order module param, wil6210 fails to load
because there are not enough Rx buffers.
Fix this by enlarging number of Rx buffers at startup, if needed based
on rx_ring_order.
