H A Dtxrx.c70801e1b Mon Dec 01 07:36:03 CST 2014 Vladimir Kondratiev <qca_vkondrat@qca.qualcomm.com> wil6210: Rate limit "ring full" error message

In the wil_tx_ring, error message printed when tx attempted
while vring has no space to accommodate all fragments of frame.
Normally, such situation handled by stopping tx queue.
But, if tx queue is by-passed (like pktgen does), this error
will be triggered at high rate and dmesg will be flooded with
this message. Whole system may become unstable and hang with
no possible recover except power cycle.

Rate-limit it to prevent dmesg flooding.
