Subject: [PATCH v3 22/33] net/ena/hal: rework Rx ring submission queue
Date: Wed, 6 Mar 2024 14:24:34 +0200	[thread overview]
Message-ID: <20240306122445.4350-23-shaibran@amazon.com> (raw)
In-Reply-To: <20240306122445.4350-1-shaibran@amazon.com>

From: Shai Brandes <shaibran@amazon.com>

RX ring submission queue descriptors are always located in host memory
This optimization replaces the generic update tail method with a
tailored method for host memory type descriptors to avoid unnecessary if
statement.
