Subject: [PATCH net-next v2] net: allow rps/rfs related configs to be switched
From: Jason Xing <kernelxing@...cent.com>
After John Sperbeck reported a compile error if the CONFIG_RFS_ACCEL
is off, I found that I cannot easily enable/disable the config
because of lack of the prompt when using 'make menuconfig'. Therefore,
I decided to change rps/rfc related configs altogether.
