Subject: [PATCH 07/10] net: netconsole: use net_eth_to_udp() for packet parsing
Date: Thu, 02 Apr 2026 08:36:46 +0200 [thread overview]
Message-ID: <20260402-net-eth-do-udp-v1-7-af5d9fd6beec@pengutronix.de> (raw)
In-Reply-To: <20260402-net-eth-do-udp-v1-0-af5d9fd6beec@pengutronix.de>
Replace the separate net_eth_to_udp_payload() and net_eth_to_udplen()
calls with the new consolidated net_eth_to_udp() helper.
