[dpdk-dev] [PATCH 1/2] net/bnxt: fix resource qcap list handling

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

[-- Attachment #1: Type: text/plain, Size: 1674 bytes --]

From: Jay Ding <jay.ding@broadcom.com>

The size of resource qcap list could be different when FW
and application are not match. Application should be able
to handle it when the FW is older and the size of qcap is
smaller.

This patch is needed for backward compatibility on older
firmware versions.
