[PATCH 08/13] net/bnxt: fix LRO offload capability

[Ajit Khaparde <ajit.khaparde@broadcom.com>]

Fix LRO offload capability for P7 devices.
Export the capability to the application only if compressed
Rx CQE mode is not enabled.

LRO aka TPA is not supported when compressed CQE mode is set.

Fixes: 3b56c3ffc182 ("net/bnxt: refactor code to support P7 devices")
