[dpdk-dev] [PATCH v2 3/7] net/bnxt: fix RSS hash configuration

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

While configuring RSS, the FW needs to know the rss_hash_mode that needs
to be initialized.
Set hash mode to HWRM_VNIC_RSS_CFG_INPUT_HASH_MODE_FLAGS_DEFAULT
to allow the FW to use the global mode already configured in the device.

Fixes: bcd4bcc4426f ("net/bnxt: configure RSS")
