3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Larry Finger <larry.fin...@lwfinger.net> commit ccae0e50c16a7f7adb029c169147400d1ce9f703 upstream. Bastian Bittorf reported that some of the silent freezes on a Linksys WRT54G were due to overflow of the RX DMA ring buffer, which was created with 64 slots. That finding reminded me that I was seeing similar crashed on a netbook, which also has a relatively slow processor. After increasing the number of slots to 128, runs on the netbook that previously failed now worked; however, I found that 109 slots had been used in one test. For that reason, the number of slots is being increased to 256. Signed-off-by: Larry Finger <larry.fin...@lwfinger.net> Cc: Bastian Bittorf <bitt...@bluebottle.com> Signed-off-by: David S.
