[gentoo-user] net-misc/dhcpcd-4.0.1-r1 change of USE flags

[Mick]

I upgraded from net-misc/dhcpcd-3.2.3 to net-misc/dhcpcd-4.0.1-r1.  I noticed 
that the vram USE flag is now removed and the compat USE flag added (to 
enable command line compatibility with the dhcpcd-3.x version).

Unfortunately, this change was also noticed by my router, which will no longer 
serve the static IP address that I have set up on it for my laptop.  I recall 
a similar problem occurring with a previous version and the solution was to 
add the vram USE flag.  I could of course ring up the router manufacturers 
and have a go at their router implementation - but hey, they may just find my 
behaviour a tad unreasonable.  ;-)

What happens is that without the vram flag the router reads not the MAC 
address of, say:

01:00:1B:2F:A7:01:DF

but something like this instead:

FD:65:74:68:90:00:01:01:00:0E:95:9F:D7:01:00:1B:2F:A7:01:DF

In other words, the router receives a ClientID probably based on the DUID 
field which is not recognised by the router as the correct MAC.

I can set the correct IP address manually at the laptop, but what I'd rather 
have is a dhcpcd implementation that works with, not against my router and 
the fields that it expects to read.  What shall I do, have a go at the router 
manufacturer all the same?
