My guess is that you are using the REQUIRE_SYMBOL() macro.  The usage of 
this macro changed to address an issue with current versions of binutils:

   http://git.ipxe.org/ipxe.git/commitdiff/fbc4ba4

All code in the tree was fixed up to meet the new usage requirements: 
you should be able to figure out the required fix from looking at the 
changes in that commit.

However, an even simpler fix should be to just add the relevant 
PCI_ROM() line to drivers/net/intel.c, which already supports the igb NIC.
