[ovs-dev] table features

[YAMAMOTO Takashi]

hi,

it seems master produces table-features with NXM_0, NXM_1,
and even packet_regs for OF1.3.

i don't think it's a good idea to include NXM stuff
because the OF standard doesn't seem to define how to parse them.
(the size of OXM ids are class-dependant)

packet_regs seems like an OF1.5 stuff which should not be included
when speaking OF1.3.

i wrote a workaround for LINC but it's better to be fixed in OVS.

how do you think?
