Hi,
did somebody already did some effort to support the intel 82579 Gigabit Ethernet PHY with the e1000 driver?
I have not tried 82579 in particular but back when I brought up our i210/i211 based modules I do remember that one at least as a bare minimum would have to add its PCI device ID to the following table:
http://git.denx.de/?p=u-boot.git;a=blob;f=drivers/net/e1000.c;h=875682b 1b89e1ee31b7226e646be3c108b850933;hb=HEAD#l73
Looking at the mainline Linux 82579 support you also may have to add some specific automatic PHY configuration (un-)gating. Plus more advanced features like EEE LPI, ME or jumbo frames may need more work but are probably not required in a boot loader.
In my naive try to add it i had no success yet.
Then enabling debugging and looking at whether the driver gets called from the PCIe side of things at all and later how far it gets in bringing the Ethernet linke up will help.
