Subject: [TULIP]: NAPI full quantum bug.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=c6a1b62de9d043f274ec3ae2e207908c6d5feff3;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

[TULIP]: NAPI full quantum bug.

This should fix the kernel warn/oops reported while routing.

The tulip driver has a fencepost bug with new NAPI in 2.6.24
It has an off by one bug if a full quantum is reached.
