Subject: Bluetooth: 6lowpan: Fix imtu & omtu values
X-Git-Url: http://git.cdn.openwrt.org/?a=commitdiff_plain;h=301de2cb6a521405cde1a2f9cdc42c5257b5725b;p=openwrt%2Fstaging%2Fblogic.git

Bluetooth: 6lowpan: Fix imtu & omtu values

The omtu value is determined by the remote peer so there's no point in
trying to hard-code it to any value. The IPSP specification otoh gives
a more reasonable value for the imtu, i.e. 1280.
