In fact it's not so heavy, it is  not socket can architecture based!!!
I copied some of linux socket can based  ->driver part<-  of codes and 
added a small wrapped layer(by myself)
only because i am too lazy to rewrite the sja1000 driver.

For blocked or unblocked access problem, it does support both.
To me, i agree mike's view if i write the sja1000 driver from scratch:)
