From: Michael Chan <michael.chan@...adcom.com>
To: davem@...emloft.net
Cc: netdev@...r.kernel.org
Subject: [PATCH net-next 05/14] bnxt_en: Add the new firmware API to query hardware resources.
The new API HWRM_FUNC_RESOURCE_QCAPS provides min and max hardware
resources. Use the new API when it is supported by firmware.
Signed-off-by: Michael Chan <michael.chan@...adcom.com>
