dcb currently sends all netlink messages with a type RTM_GETDCB, even the
set ones. In patch #1, send the setters as RTM_SETDCB.
In patch #2, plug a leak.
In patch #3, change the command line option for namespace change from
devlink-like -N / --Netns to ip-like -n / --netns.
v2:
- Patches #1-#3:
- Add Fixes: tag.
Petr Machata (3):
dcb: Set values with RTM_SETDCB type
dcb: Plug a leaking DCB socket buffer
dcb: Change --Netns/-N to --netns/-n

DCB socket buffer is allocated in dcb_init(), but never freed(). Free it
in dcb_fini().

This to keep compatible with the major tools, ip and tc. Also
document the option in the man page, which was neglected.
