This is a substantial change to the EM driver that I would appreciate some testing and feedback on.
You just replace the two files in your STABLE tree. Its big enough that this seemed easier than a patch. Whats in this: A change Mike Silbersack came up with, it makes the watchdog period twice as long, but then in the middle of it fires off a clean. Thats a small change. Secondly, I took the locking mechanism I used in ixgbe and added it here. It uses two locks: core and tx instead of one. Third, added the EEPROM dumper into the driver, if you do `sysctl dev.em.X.debug=2' it will dump 32 words worth of the prom, this will allow an easy way to tell if you need a patch to an 82573 for instance. Next, I found a serious bug for Zoar (82575) users, it had to do with how and when I decide to try and use MSI/X, the fact that no one has squawked about this must mean all users are running 7 :) cuz on STABLE right now the driver load will FAIL if you enable MSI/X on the system. What I did was to create a new function for setting up msi and msix, its much cleaner and fixes this problem. In any case, I have done some pounding on this but wider testing would be good, let me know what you find. I hope to get this all resolved and into the tree for 6.3. Jack
