Subject: [PATCH 10/17] octeontx2-af: Enable packet length and csum validation
Date: Fri, 19 Oct 2018 19:07:31 +0530 [thread overview]
Message-ID: <1539956258-29377-11-git-send-email-sunil.kovvuri@gmail.com> (raw)
In-Reply-To: <1539956258-29377-1-git-send-email-sunil.kovvuri@gmail.com>
From: Sunil Goutham <sgoutham@marvell.com>
Config NPC layer info from KPU profile into protocol
checker to identify outer L2/IPv4/TCP/UDP headers in a
packet. And enable IPv4 checksum validation.
L3/L4 and L4 CSUM validation will be enabled by PF/VF
drivers by configuring NIX_AF_LF(0..127)_RX_CFG via mbox
i.e 'nix_lf_alloc_req->rx_cfg'
Also enable setting of NPC_RESULT_S[L2B] when an outer
L2 broadcast address is detected. This will help in
installing NPC MCAM rules for broadcast packets.
