[lvc-project] [PATCH BlueZ 2/2] a2dp: enable input MTU auto-tuning for the server

[Fedor Pchelkin]

L2CAP frames are lost while utilizing some exotic A2DP transports
usually coming up with weird custom MTU sizes so take advantage of
auto-tuning it for such cases.

Found by Linux Verification Center (linuxtesting.org).
