Re: SiS900: NULL pointer encountered in Rx ring, skipping

[Dominik Karall <dominik.karall@gmx.net>]

After doing some changes in the /proc/sys/, it works now without problems!
My settings:

net.ipv4.tcp_keepalive_time=3600
net.ipv4.tcp_rmem=4096 25165824 25165824
net.core.rmem_max=25165824
net.core.rmem_default=25165824
net.ipv4.tcp_wmem=4096 65536 25165824
net.core.wmem_max=25165824
net.core.wmem_default=65536
net.core.optmem_max=25165824
