[LTP] [PATCH v5 0/2] Route tests using netlink API (dst,gw,if)

[Petr Vorel]

Hi,

changes v4->v5:
* add implementation for changing interface
* lib: turn setup_addrinfo() into SAFE_GETADDRINFO() (1st commit)

route-change-netlink.c
* remove -l lhost parameter, interfaces are still created
* fixes required by Alexey:
  - use struct addrinfo. I still use char array for printing name, moved
	to the end (better for struct packing)
  - optimize char to numeric address conversion and string manipulation
	to get route destination (moved from test to setup, thus done fewer times)
  - use callback in save_item
  - change delimiter to ','

  - renamed functions

TODO:
* some further code cleanup is probably required.
* NS_TIMES=10 isn't really high enough.
shell tests could have 100 (there are some problems when higher than
300), but C tests could have it much higher (eg. 2000, but I've
tested it with the max 65535). Maybe there could be ROUTE_NS_TIMES and
ROUTE_NETLINK_NS_TIMES variables to not affect other tests which use
NS_TIMES.

Kind regards,
Petr
