From 6c71b0ea761da416af54df4f72f48e71050cc012 Mon Sep 17 00:00:00 2001 From: Juuso Oikarinen Date: Thu, 18 Feb 2010 13:25:48 +0200 Subject: [PATCH] wl1271: Optimized RX path packet retrieval Instead of acking RX packets read from the FW once all (of several possible) buffered packets are retrieved, ack packets one by one as they are read. This enables the FW to start receiving more packets from the network while the host read operation is still ongoing. Signed-off-by: Juuso Oikarinen Reviewed-by: Kalle Valo Signed-off-by: John W.
