Subject: [dpdk-dev] [PATCH 04/10] net/bnxt: add changes to support 2 table scopes
Date: Mon, 13 Jul 2020 11:45:54 +0530 [thread overview]
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.
