Subject: [PATCH net] net: enetc: correct the value of ENETC_RXB_TRUESIZE
Date: Fri, 10 Oct 2025 17:26:08 +0800 [thread overview]
Message-ID: <20251010092608.2520561-1-wei.fang@nxp.com> (raw)
ENETC_RXB_TRUESIZE indicates the size of half a page, but the page size
is adjustable, for ARM64 platform, the PAGE_SIZE can be 4K, 16K and 64K,
so a fixed value '2048' is not correct when the PAGE_SIZE is 16K or 64K.
Fixes: d4fd0404c1c9 ("enetc: Introduce basic PF and VF ENETC ethernet drivers")
Signed-off-by: Wei Fang <wei.fang@nxp.com>
