Subject: ath6kl: increase usb rx buffer size to 4096
X-Git-Url: http://drtracing.org/?a=commitdiff_plain;h=987cdcba62da369d41f61bb1026d40d670c4efe6;p=deliverable%2Flinux.git

ath6kl: increase usb rx buffer size to 4096

With the previous value (1700), some urb are dropped
with a babble error (urb status equal -EOVERFLOW).

These error seems to only happen when urb length is a
multiple of packet size (512).
