Subject: [dpdk-dev] [PATCH 04/13] net/bnxt: fixes for PMD PF support in SR-IOV mode
Date: Fri, 9 Oct 2020 16:41:21 +0530 [thread overview]
Message-ID: <20201009111130.10422-5-somnath.kotur@broadcom.com> (raw)
In-Reply-To: <20201009111130.10422-1-somnath.kotur@broadcom.com>
From: Venkat Duvvuru <venkatkumar.duvvuru@broadcom.com>
1. Implement HWRM_FUNC_VF_RESOURCE_CFG command and use it to
reserve resources for VFs when NEW RM is enabled.
2. Invoke PF’s FUNC_CFG before configuring VFs resources.
3. Don’t consider max_rx_em_flows in max_l2_ctx calculation
when VFs are configured.
4. Issue HWRM_FUNC_QCFG instead of HWRM_FUNC_QCAPS to find
out the actual allocated resources for VF.
5. Don’t add random mac to the VF.
6. Handle completion type CMPL_BASE_TYPE_HWRM_FWD_REQ instead
of CMPL_BASE_TYPE_HWRM_FWD_RESP.
7. Don't enable HWRM_FUNC_DRV_RGTR_INPUT_FLAGS_FWD_NONE_MODE
when the list of HWRM commands that needs to be forwarded
to the PF is specified in HWRM_FUNC_DRV_RGTR.
8. Update the HWRM commands list that can be forwared to the
PF.
Fixes: b7778e8a1c00 ("net/bnxt: refactor to properly allocate resources for PF/VF")
