[linux-vrf-core] [PATCHLET] Check ioctl parameters.

[Yon U. <hav...@gm...>]

Hi,

Do not happily overwrite memory. A better solution could be to just
#define VRF_MAX 256
and forget about it (there is cast in the af_inet.c call, so the check
would be redundant). Wasted memory is not an issue ( less than 1Kbyte).

And a happy new year,
 yon
