The changes for locking the network stack have been going on for >2 
years.  During that time I and many others have called for people to 
help.  At some point you have to leave certain code behind or you'll 
never make progress.  Robert Watson made the extra effort to provide 
legacy support for drivers that lacked proper locking (I intended to 
just leave them broken until someone stepped up and fixed them). That 
this particular driver broke regardless is unfortunate but 
inconsequential relative to other issues.  Given the price of 100baseT 
NICs these days if you're not willing to fix the code yourself I don't 
see it as a massive hardship to go buy replacements for your de cards.
