Subject: [PATCH v1] net: dhcp: send current hostname as part of the DHCP request
Date: Tue, 14 Sep 2021 08:30:01 +0200 [thread overview]
Message-ID: <20210914063001.2803749-1-o.rempel@pengutronix.de> (raw)
To be able to use more advanced DHCP server configurations, for example
host name pattern matching, barebox should send some name.
With this patch, barebox will send barebox_hostname, if dhcp.hostname is
not configured.
