Subject: Spidernet Avoid possible RX chain corruption
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=df519ab2c5a774e813459fcb3e3d080276baa7d8;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

Spidernet Avoid possible RX chain corruption

Delete possible source of chain corruption; the hardware
already knows the location of the tail, and writing it
again is likely to mess it up.
