Hi
X552 10G NIC drivers is not enabled in upstream kernel yet due to without
adding x552 pciid into supported device id table.
With attached patch, netdev interface could be created successfully as below:
[root@localhost linux]# lspci | grep Eth
00:19.0 Ethernet controller: Intel Corporation Ethernet Connection (2) I218-V
(rev 05)
02:00.0 Ethernet controller: Intel Corporation Ethernet Connection X552 10 GbE
SFP+
[root@localhost linux]# lspci -ns 02:00.0
02:00.0 0200: 8086:15ac <-- defined as IXGBE_DEV_ID_X550EM_X_SFP MACRO in
driver
But without adding into pci id table.

But Ixgbe driver couldn't recognize SFP module I attached by return
IXGBE_ERR_SFP_NOT_PRESENT ,
it's a AFBR-703SDZ-IN2 850nm LASER PROD, SN: AD1329102DU, a little debug shows
it fails with a i2c
read errors if I remember correctly. BTW SFP modules works ok with 82599EB NIC,
and my custom also
spot the identical failure.
So may I query:
1. whether x552 NIC is supported by current kernel ixgbe driver after I updated
pciid table for it?
2. Any other hints to enable x552 NIC now?
3. Is there any public docs to state which SFP module is supported by x552?
Thanks a lot!
