[Linux-zigbee-devel] [PATCH 3/7] 6lowpan: remove several copies of sk_buff

2013-09-28 Thread Alexander Aring
The current implementation does many copies of the sk_buff for increasing headroom which are not necessary. This patch increases the headroom in the maclayer for a worst case scenario of (sizeof(struct ipv6hdr) + sizeof(struct udphdr)). Signed-off-by: Alexander Aring Acked-by: Werner Almesberger
