From 0c19744c344cf1bfda04f681ff4e1e46455577bd Mon Sep 17 00:00:00 2001 From: Johannes Berg Date: Thu, 15 Mar 2012 13:26:43 -0700 Subject: iwlwifi: process multiple frames per RXB The flow handler (hardware) can put multiple frames into a single RX buffer. To handle this, walk the RX buffer and check if there are multiple valid packets in it. To let the upper layer handle this correctly introduce rxb_offset() which is needed when we pass pages to mac80211 -- we need to know the offset into the page there. Also change the page handling scheme to use refcounting. Anyone who needs a page will "steal" it, which marks it as having been used & refcounts it. The RX handler then has to free its own reference and must not reuse the page. Finally, do not set the bit asking the FH to give us each packet in a single buffer. This really enables the feature.
