How to add noprefixroute flag when adding address?

[tsv1991]

Hi,
we use next one construction:

ipr = IPRoute()
ipr.link('add', ifname='br8888', kind='bridge', mcast_snooping=0)
ifindex_br = ipr.link_lookup(ifname='br8888')[0]
ipr.addr('add', index=ifindex_br, address="169.254.169.254", mask=24, scope=253)

How we can add flag noprefixroute when use ipr.addr?
Used the ip utility we do it like: ip a add 169.254.169.254/24 dev br8888 noprefixroute

I did it like that:
flags=0x200
ipr.addr('add', index=ifindex_br, address="169.254.169.254", mask=24, scope=253, flags=0x200)

I believe that the bridge options should be prefixed with br_:

ipr.link('add', ifname='br8888', kind='bridge', br_mcast_snooping=0)

Regarding the address there are flags defined in pyroute2.netlink.rtnl.ifaddrmsg:

pyroute2/pyroute2/netlink/rtnl/ifaddrmsg.py

Lines 15 to 27 in 696d2bf

	IFA_F_SECONDARY = 0x01
	# IFA_F_TEMPORARY IFA_F_SECONDARY
	IFA_F_NODAD = 0x02
	IFA_F_OPTIMISTIC = 0x04
	IFA_F_DADFAILED = 0x08
	IFA_F_HOMEADDRESS = 0x10
	IFA_F_DEPRECATED = 0x20
	IFA_F_TENTATIVE = 0x40
	IFA_F_PERMANENT = 0x80
	IFA_F_MANAGETEMPADDR = 0x100
	IFA_F_NOPREFIXROUTE = 0x200
	IFA_F_MCAUTOJOIN = 0x400
	IFA_F_STABLE_PRIVACY = 0x800

Also there are static functions to convert flags, like that:

from pyroute2.netlink.rtnl.ifaddrmsg import ifaddrmsg

ipr.addr(
    'add',
    index=ipr.link_lookup(ifname='br8888'),  # index can be provided as an iterable, the [0] item will be used
    address="169.254.169.254",
    prefixlen=24,
    scope=253,
    flags=ifaddrmsg.names2flags(["IFA_F_NOPREFIXROUTE"])
)

May be syntax like flags=["noprefixroute"] would be simpler; it would be easy to add, I think.

I think this looks like more right way, because it seems universal.
