unit: give systemd-networkd.socket a better description Usually we try to properly uppercase first characters in the description, do so here, too. Also, keep it close to the string used in systemd-networkd.service. 2015-10-06 16:24:02 +08:00			`Description=Network Service Netlink Socket`

systemd-networkd.socket: Add conflict with shutdown.target (#19348) systemd-networkd.socket can re-start systemd-networkd.service in shutdown and by doing this even stop shutdown.target leaving the system in halfway-down state.

network: bump netlink receive buffer size to 128M Prompted by #14417. 2019-12-26 14:29:26 +08:00			`ReceiveBuffer=128M`

networkd: clean up NETLINK_PKTINFO vs. SO_PASSCRED confusion We actually care for NETLINK_PKTINFO, not for SO_PASSCRED, hence when allocating the netlink socket, configure things accordingly.
