As far as I'm aware, this list is complete.  I compiled it by identifying all 
network device drivers that set (or may set) the IFF_NEEDSGIANT.  With respect 
to i2c, this refers *only* to the if_ic.c network device driver, and not the 
other services associated with i2c, so bktr and other i2c consumers should be 
unaffected.  I'm not familiar with cxm so can't comment on that.  If you are 
aware of any other in-tree network device drivers that use IFF_NEEDSGIANT and 
aren't on the list, please do let me know.
