NetBSD 6.1 says:

In src/sys/dev/pci/ixgbe/ we know about producct Id 0x1529 and 0x152A but
not 0x1528. But this can probably be easily borrowed from FreeBSD:
http://svnweb.freebsd.org/base/head/sys/dev/ixgbe/

They call it IXGBE_DEV_ID_X540T, You can try to add in ixgbe_type.h:
#define IXGBE_DEV_ID_82599_X540T 0x1528

Then in ixgbe.c add a IXGBE_DEV_ID_82599_X540T line in
ixgbe_vendor_info_array[]

In ixgbe_82599.c you need a case IXGBE_DEV_ID_82599_X540T
next to case IXGBE_DEV_ID_82599_BACKPLANE_FCOE if media
is indeed backplane. Otherwise add it at the appropriate place
in the switch statement.

And finally you need to add a case IXGBE_DEV_ID_82599_X540T
next to case IXGBE_DEV_ID_82599_BACKPLANE_FCOE in ixgbe_api.c

Our ixg(4) driver doesn't support X520. At least there is no

s/X520/X540/

file ixgbe/ixgbe_x540.c of FreeBSD.
