Subject: [PATCH v3 08/17] net/txgbe: fix reserved extra FDIR headroom
Date: Fri, 13 Jun 2025 16:41:50 +0800	[thread overview]
Message-ID: <20250613084159.22184-9-jiawenwu@trustnetic.com> (raw)
In-Reply-To: <20250613084159.22184-1-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")
