Subject[PATCH 5.10 092/103] net: mvneta: fix error message when MTU too large for XDP
Date
From: Marek Behún <kabel@kernel.org>

commit 0d136f5cd9a7ba6ded7f8ff17e8b1ba680f37625 upstream.

The error message says that "Jumbo frames are not supported on XDP", but
the code checks for mtu > MVNETA_MAX_RX_BUF_SIZE, not mtu > 1500.

Fix this error message.
