Subject: [PATCH v2 12/17] octeontx2-af: Add LMAC channel info to NIXLF_ALLOC response
Date: Mon, 22 Oct 2018 23:25:59 +0530 [thread overview]
Message-ID: <1540230964-5506-13-git-send-email-sunil.kovvuri@gmail.com> (raw)
In-Reply-To: <1540230964-5506-1-git-send-email-sunil.kovvuri@gmail.com>
From: Stanislaw Kardach <skardach@marvell.com>
Add LMAC channel info like Rx/Tx channel base and count to
NIXLF_ALLOC mailbox message response. This info is used by
NIXLF attached RVU PF/VF to configure SQ's default channel,
TL3_TL2_LINKX_CFG and to install MCAM rules in NPC based
on matching ingress channel number.
