Currently set to 1, which means that a packet quickly following another pushed by PPP must wait until hardware actually sends the previous and PPP has to be waken up by ppp_wakeup(). This slows down upstream. Now PPP can push more packets at once which get buffered inside driver and pushed immediatelly to hardware when previous packet is out. Experiments show that size = 10 is quite good for all connection types (GPRS/EDGE/UMTS) and gains 4 KB/sec of upload for UMTS for batch uploads. Need for higher queue size than 10 occures in only < 0.1 % of cases. Signed-off-by: David Sterba Signed-off-by: Jiri Kosina Signed-off-by: Linus Torvalds --- Reading git-diff-tree failed
