Subject: [PATCH] net/tap: Allow jumbo frames
Date: Mon, 8 Aug 2022 11:31:16 +0200 [thread overview]
Message-ID: <315474c3-7004-2114-9e24-8344da7aca9e@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.
