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?).
