[PATCH BlueZ v1] l2test: Attempt to use BT_SNDMTU if output MTU has been set

[PATCH BlueZ v1] l2test: Attempt to use BT_SNDMTU if output MTU has been set

[Luiz Augusto von Dentz]

From: Luiz Augusto von Dentz <luiz.von.dentz@intel.com>

With the suggested fixes for L2CAP/ECFC/BV-27-C the kernel shall be
able to accept setsockopt(BT_SNDMTU) in order for an applications
to require a minimal output MTU greater than 64.

Fixes: https://github.com/bluez/bluez/issues/1895
