2020-04-15pg: set vnet buffer flags in pg streamsDave Barach5-1/+40
See .../extras/pg/checksum_offload.pg for a nontrivial example, which deliberately sets bogus ip and udp checksums in the generated packets, then fixes the mess with (software emulated) hardware checksum offload. Validated via "pcap dispatch trace on max 1000 buffer-trace pg-input 100". Packets stuffed into loop1-output have the configured bogus ip and udp checksums. vnet_calc_checksums_inline(...) fixes the checksums, which are correct when packets visit loop1-tx. The packet generator is a dumb robot in this regard. If you ask for a ridiculous flag combination - example: ip4 and ip6 - your mileage may vary.

2020-04-15misc: refactor calc_checksumsDave Barach5-81/+64
Merge two mildly incompatible static inlines, and rename the results vnet_calc_checksums_inline (...). The resulting inline has three additional parameters: int is_ip4, int is_ip6, and int with_gso. All calls manage to pass one or more as compile-time constants, which causes a certain amount of code to disappear in each instantiation.
