Now this is my first attempt at editing src :-)
so under igb there is only a Makefile

dfly-bkpsrv# cd igb
dfly-bkpsrv# pwd
/usr/src/sys/dev/netif/e1000/igb
dfly-bkpsrv# ls
Makefile
dfly-bkpsrv# cat Makefile
. PATH:  ${.CURDIR}/../../../../dev/netif/e1000

KMOD=   if_igb
SRCS=   if_igb.c
SRCS+=  e1000_80003es2lan.c e1000_82540.c e1000_82541.c e1000_82542.c
e1000_82543.c
SRCS+=  e1000_82571.c e1000_82575.c e1000_api.c e1000_ich8lan.c e1000_mac.c
SRCS+=  e1000_manage.c e1000_nvm.c e1000_osdep.c e1000_phy.c
SRCS+=  device_if.h bus_if.h pci_if.h
SRCS+=  opt_polling.h opt_ktr.h

. ifndef BUILDING_WITH_KERNEL
opt_polling.h:
        echo '#define DEVICE_POLLING 1' > ${.OBJDIR}/${.TARGET}
. endif

. include <bsd.kmod.mk>

Where do I put the PCI IDs in this file?

O should I copy the FreeBSD driver files for this chipset and then add
those files here?

For FreeBSD the files is src are
