From 143b09efb74efd3328f57d7a4bd6d7663c1d6497 Mon Sep 17 00:00:00 2001 From: Tomas Winkler Date: Thu, 24 Jul 2008 21:33:42 +0300 Subject: [PATCH] iwlwifi: don't stop queue in the middle of fragmented packet This patch avoids stopping queue in the middle of the fragmented packet. It is required that there will be ~10 (max packet/min fragment) or 16 (4 bits of frag number) free tfds all the time. Signed-off-by: Tomas Winkler Signed-off-by: John W.
