Oleksandr Tymoshenko 031d577716 Increase TX_MAX_SEGS from 10 to 20 for the if_awg.c driver 
Under certain traffic pattern awg driver does not recover from TX queue
full condition. The actual source of the problem is not identified yet
but jmcneill@ agreed that bumping TX_MAX_SEGS to 20 is OK as a workaround
for the problem (NetBSD has it set to 128).

Also add some diagnostic printfs to prevent silent failure of bus_dma
functions in the future

PR will be kept open until root cause of the issue is identified and fixed
