From 9ee1ba474fc37bcaf6a958bf7e995006fc69893b Mon Sep 17 00:00:00 2001 From: Ron Rindjunsky Date: Mon, 26 Nov 2007 16:14:42 +0200 Subject: iwlwifi: 802.11n add support to 8K A-MSDU Rx frames This patch give the iwlwifi the ability to support A-MSDU up to 8K Please notice - in order to work in 8K A-MSDU ucode support is needed, version 4.44.1.19 (soon to be published). 4K A-MSDU works in current ucode version as well.
