[net+iproute2,0/2] nbyte, cmp and text filter fixups

The iproute2 part allows the the actual use of the already existing
quoted string parsing.

The kernel side fixes an oob read in em_nbyte and allows 'layer 0' in
cmp and nbyte (and em_text whose existence surprised me given that I did
not see it exposed via iproute2) to actually match layer 0 rather than
being the same as specifying layer 1.

I seem to have stumbled upon a layer of dust (says git-blame).
Trying to match mac addresses I felt that the examples found online
using the 'u32' filter were rather inconvenient, particularly given
that there's the 'nbyte' filter around that could just memcmp the
entire a byte sequence at once.

Makes no sense to send iproute2 patch which is not related with the
kernel ones in the same set. Please send it separatelly.

"net: sched:" or "net_sched:"? - please, try to be consistent
