Re: fxp hack in sys/net/if.c?

The reasoning behind moving the delay in to shared code is not very compelling.

From "cvs blame":

Add workaround for fxp issue at interface initialization with IPv6.

 Some LAN card chip for fxp is known to cause problem at
 interface initialization with IPv6 enabled. It happens at
 some delicate timing.
 And also, just adding some DELAY before IPv6 address
 autoconfiguration is known to avoid the problem.

 Complete fix is changing the driver not to use interrupt at
 multicast filter initialization, but trying such change in
 this stage will be dangerous.

 So I add some DELAY() only inside #ifdef INET6 part,
 as temporal workaround only for 4.0.

Hi,

could anyone having a clue why that is there look at it and either
remove it or remove it and properly handle it elsewhere?

I have continuesly noticed it for a while so I think the "temporary"
as given in the comment rather means "forgotten"?
