[Bug 654937] [NEW] r8192se_pci: rtl8191SEVA2 fails to transmit certain mumble packets

[Steve Langasek]

Public bug reported:

Trying to use a new laptop with the Canonical mumble server, I have
found that the rtl8191SEVA2 wireless card fails to send certain packets
out.  This is shown in the packet captures I'll be attaching shortly:
packet 23 in 'mumble-local.pcap', as well as all subsequent
retransmission attempts, never make it to the gateway (mumble-
inside.pcap).

This is reproducible with both a lucid and a maverick kernel, and has
been tested on multiple different wireless networks (with different
routers).  If I connect the laptop over ethernet instead, it has no
difficulty connecting to mumble.

A cursory examination of the troublesome packet doesn't tell me what
makes it different from other packets.  I have not noticed any other
connection problems or slow connections that would suggest there are
other retransmission problems, only when connecting to mumble; and the
problem is 100% reproducible when connecting to the mumble server.
