[dpdk-dev] [PATCH] igb_ethdev.c: complete switches for i211 NC

[Sergey Mironov <grrwlf@gmail.com>]

Hi! I have got an update for my "i212 problem". First of all, I found
that I have made a mistake. My controller is named i211, not i212 :)
Next, i211 controller is controlled by the lib_pmd_e1000 driver.
Unfortunately, looks like it's support is pure. For example,
igb_ethdev.c contains function eth_igb_infos_get() which should set
number of tx/rx queues supported by the hardware. It contains huge
[switch] but there is no i211 case! That is why I see zeros every time
I try to start this NC. Also, there are few other places which mention
i210, but not mention i211. I've attached a patch which adds necessary
i211 support, but I didn't check it enough to say it is totally
correct. For now I see that it just able to send and receive some
packets.

Could you please review/correct it?
