VPP-1001 - update AF Packet Driver to for modern kernels
1. Add VNET headers support for checksumming - required
to operate correctly on any recent Linux
2. Bypass QDISC on transmit - improves performance by ~ 5%.
Enabled only if the macro is detected - apparently not
present on archaic distributions.
This still does not solve all issues with TSO - it can be
fixed only by going to tpacket v3 and dynamic rx ring as
well as significant changes in the TX (sendmmsg?).
