Bug 27862

Summary:	xl driver defaults to incorrect broadcast address
Product:	Base System	Reporter:	tundra

Status:	Closed FIXED
Severity:	Affects Only Me

Description tundra 2001-06-03 23:30:01 UTC

Running a 3c509C in a non-routable address space being set up in
rc.conf as follows:

ifconfig_xl1="inet 192.168.0.254 netmask 0xfffff00"

This setup defaults to a broadcast address of 240.168.0.255 which
I believe is bogus - it should be 192.168.0.255 - this seems to
confuse programs like 'samba' that need broadcasting to work
correctly.

Fix: 

Use the following line in rc.conf:

ifconfig_xl1="inet 192.168.0.254 netmask 0xfffff00 broadcast 192.168.0.255"

I believe that this should be 0xffffff00.
(Note: 8 characters after the '0x')
With the input you have given (which is bogus), 
the results seem to be appropriate (though probably not meaningful).

Please try correcting this and report back on the results.

I too hastily assigned this PR. The originator has a typo, the netmask 
should be 0xffffff00, or more easily understood by humans, 255.255.255.0.

I erred in A) not reading the PR more carefully, and B) bothering wpaul with it.

Many apologies (I am such a moron) ... old age and long hours are my
only excuse.  The correct mask, does, of course work properly.
