Subject: [PATCH net-next v6 13/13] net: mana: keep the existing queues when the channel count is raised
Date: Fri, 9 Oct 2026 14:41:24 +0000 [thread overview]
Message-ID: <6243b02cc7140a9ff340dbdb8b770d22b19ddb9b.1790795005.git.weh@linux.microsoft.com> (raw)
In-Reply-To: <cover.1790795005.git.weh@linux.microsoft.com>
From: Long Li <longli@microsoft.com>
Keep existing queues and allocate only the added tail. Growing N to M
now needs M SQ/RQ pairs at peak, rather than N + M.
Track the fresh queues separately for failure cleanup and XDP references.
Wait for TX-selection readers before freeing old containers, and clear
slots during partial teardown. Full rebuilds now keep the current count.
Advertise in-driver resize recovery after converting the live resize
paths. Failed rollback still requires recovery.
