rG5189261cd0ec: libmlx5: Report SW parsing capabilities through mlx5 direct verbs
Summary

[PATCH 24/31] FreeBSD OFED support for DPDK MLX5 PMD

Software parsing (SWP) is a feature that can be used to instruct the
device to stop using its internal parser and to parse packets on the
transmit path according to offsets set for each packet.

Through this feature, the device allows the handling of checksum and LSO
by the hardware according to the location of IP and TCP/UDP headers.

Report various SW parsing capabilities and supported QP types through
mlx5 direct verbs interface.

Test Plan

Tested on KVM, ESXi, and HyperV/Azure Hypervisors with FreeBSD 14.0-CURRENT and FreeBSD12.1-STABLE.
