It will be pushed if I get no objections before 05/12/21. So please shout if anyone has objections. Also note that after the patch there's a diff of the upstream commit vs the patch applied to the branch. This will indicate if there was any rebasing needed to apply to the stable branch. If there were code changes for rebasing (ie: not only metadata diffs), please double check that the rebase was correctly done. Queued patches are on a temporary branch at: https://github.com/steevenlee/dpdk This queued commit can be viewed at: https://github.com/steevenlee/dpdk/commit/274ff8673a91b76981f5e6dbcd88211c8c3f3bf4 Thanks.

Renamed bnxt_hwrm_alloc_vf_info()/bnxt_hwrm_free_vf_info to bnxt_alloc_vf_info()/bnxt_free_vf_info as it does not issue any HWRM command to fw. 2. Fix missing unlock when memory allocation fails.
