[PATCH] libosmo-abis[master]: lapd: Reduce N200 (SABM retransmission count)

[dexter]

Hello Jenkins Builder,

I'd like you to reexamine a change.  Please visit

    https://gerrit.osmocom.org/2010

to look at the new patch set (#2).

lapd: Reduce N200 (SABM retransmission count)

N200, which controls the maxium number of LAPD retransmissions,
is set to 300. This will cause a long waiting time until
LAPD detects a failed link. This commit reduces the retransmission
count to 50 in order to get a faster link re-establishment in
case of link failure. This patch will only affect the ericsson
LAPD profile, all other lapd profiles will not be touched.
