Bug ID: 220698
Summary: [iflib][em] some interface options flags can not
change
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---

iflib.c cleanup
The options flags VLAN_HWCSUM on if_em driver can not be changed by using
ifconfig command.
See https://lists.freebsd.org/pipermail/freebsd-net/2017-May/048008.html
The WOL_UCAST flags can't also be changed.
The attached patch makes these flags changeable. And it contains others listing
below.
1. WOL related flags can be changed without re-initialize.
2. Because of the function if_vlancap() refers the parent device flags,
I think, if_togglecapenable() is first, then if_vlancap() is next.
3. Don't check immediate number but defined value.
I don't have any problems now and it is not related to options flags,
but I think it is incorrect.
