Increase the trace bufffer size
In some cases, the packet header size with IPv6 and a tunnel can overflow the buffer used for packet tracing. This patch increases this buffer a little to avoid truncated header information in the trace. Change-Id: Ib800e3b908ebe7e80bae4428a94541a803b40b8c Signed-off-by: Chris Luke <chrisy@flirble.org>
