Subject: [PATCH 09/21] common/cnxk: fetch eng caps for inl outb inst format
Date: Tue, 11 Apr 2023 14:41:32 +0530	[thread overview]
Message-ID: <20230411091144.1087887-9-ndabilpuram@marvell.com> (raw)
In-Reply-To: <20230411091144.1087887-1-ndabilpuram@marvell.com>

Fetch engine caps and use it along with model check
to determine inline outbound instruction format
with NIX Tx offset or address.
