Hello All. For a project, I am looking into making the em(4) driver use fast interrupts. Has someone done this or are there other driver references that could help me in this?
 
I understand that the main problems are:
 
1. Sharing of interrupts.
2. Blocking (memory and mutexes).
 
Are there any other issues I might have missed?
