From: Somnath Kotur <somnath.kotur@broadcom.com> To: dev@dpdk.org Cc: ferruh.yigit@intel.com Subject: [dpdk-dev] [PATCH 04/10] net/bnxt: add changes to support 2 table scopes Date: Mon, 13 Jul 2020 11:45:54 +0530 Message-ID: <20200713061600.19456-5-somnath.kotur@broadcom.com> (raw) In-Reply-To: <20200713061600.19456-1-somnath.kotur@broadcom.com> From: Farah Smith <farah.smith@broadcom.com> Need to remap the table scope ids allocated from HCAPI RM from high to low value because for legacy devices a table scope is a set of base addresses. The PCIe addresses must map to a PCIe PF which exists in the hardware.
