dev_flags definitions in broadcom.c

Nate, On May 17, 2008 you submitted a patch titled
"PHYLIB: Add 1000Base-X support for Broadcom bcm5482".  In that patch
you defined several dev_flags definitions for the broadcom module.  I
only see the PHY_BCM_FLAGS_MODE_1000BX being used in the code though.  I
quickly scanned through the phy_connect calls in drivers/net and didn't
see any caller using this preprocessor definition or an equivalent
hardcoded constant.  Perhaps I missed something though.  Can you tell me
where these flags are set?

My interest in this is several-fold.  First, I'd like to move the
definitions to include/linux/brcmphy.h so that the same preprocessor
definitons can be used at both ends.  But more important than that, I'd
like to get a handle on how many of these definitions are actually used
and how many are just placeholders.  With only 32-bits to use, the flags
might become a precious resource.  I have plans for a few of these bits
myself, and I'd like reviewers to take note of how they are used.
