Subject: [PATCH 03/12] net/txgbe: fix reserved extra FDIR headroom
Date: Fri, 6 Jun 2025 16:01:08 +0800 [thread overview]
Message-ID: <8D9A900CA63A7BF3+20250606080117.183198-4-jiawenwu@trustnetic.com> (raw)
In-Reply-To: <20250606080117.183198-1-jiawenwu@trustnetic.com>
Remove redundant 256KB FDIR headroom reservation. FDIR headroom was
already allocated in txgbe_fdir_configure() when FDIR is enabled, the
second reservation resulted in 256KB less available RX packet buffer than
the theoretical size.
Fixes: 8bdc7882f376 ("net/txgbe: support DCB")
