ipconfig: Tidy up reporting of name servers
Commit 5e953778a2aab04929a5e7b69f53dc26e39b079e ("ipconfig: add nameserver IPs to kernel-parameter ip=") adds the IP addresses of discovered name servers to the summary printed by ipconfig when configuration is complete. It appears the intention in ip_auto_config() was to print the name servers on a new line (especially given the spacing and lack of comma before "nameserver0="), but they're actually printed on the same line as the NFS root filesystem configuration summary: [ 0.686186] IP-Config: Complete: [ 0.686226] device=eth0, hwaddr=xx:xx:xx:xx:xx:xx, ipaddr=10.0.0.2, mask=255.255.255.0, gw=10.0.0.1 [ 0.686328] host=test, domain=example.com, nis-domain=(none) [ 0.686386] bootserver=10.0.0.1, rootserver=10.0.0.1, rootpath= nameserver0=10.0.0.1 This makes it harder to read and parse ipconfig's output. Instead, print the name servers on a separate line: [ 0.791250] IP-Config: Complete: [ 0.791289] device=eth0, hwaddr=xx:xx:xx:xx:xx:xx, ipaddr=10.0.0.2, mask=255.255.255.0, gw=10.0.0.1 [ 0.791407] host=test, domain=example.com, nis-domain=(none) [ 0.791475] bootserver=10.0.0.1, rootserver=10.0.0.1, rootpath= [ 0.791476] nameserver0=10.0.0.1 Signed-off-by: Chris Novakovic <chris@chrisn.me.uk> Signed-off-by: David S.
