Subject: [PATCH 2/3] net/cnxk: support backpressure on SPB pool
Date: Thu, 15 Jun 2023 18:39:23 +0530	[thread overview]
Message-ID: <20230615130924.828208-2-ndabilpuram@marvell.com> (raw)
In-Reply-To: <20230615130924.828208-1-ndabilpuram@marvell.com>

From: Sunil Kumar Kori <skori@marvell.com>

With current implementation, backpressure can be configured only
on lpb_pool but a RQ can be configured with spb_pool too and
spb_pool can also participate to assert backpressure.

Enabling backpressure support on spb_pool for 802.3x and
802.1qbb both.
