Subject: [PATCH v5] net/tap: Allow jumbo frames
Date: Mon, 8 Aug 2022 14:29:25 +0200
Message-ID: <bcf64f0d-8afb-af19-7c0a-e7314f55f1a0@tutus.se> (raw)

eth_dev_validate_mtu, introduced in 990912e676e, validates configured
MTU plus overhead against max_rx_pktlen.
Since TAP is a virtual device, it should support as big MTU as possible.
