||

||
+ | # Looking at the Intel driver at e.g. https://elixir.bootlin.com/linux/v5.8/source/drivers/net/ethernet/intel/ixgbe/ixgbe_type.h#L2140 we can see |
||
+ | # that the bit 0x1 at Address 0x58 contains a configuration setting whether the card allows any SFP modules or if Intel specific ones are enforced |
||
+ | # by the driver. |
||
+ | # |
||
+ | # Addr Bitstring |
||
+ | # 0x58 xxxxxxx0 means Intel specific SFPs |
||
+ | # 0x58 xxxxxxx1 means any SFP is allowed. |
||
+ | # |
||
+ | # Using the parameter allow_unsupported_sfp for the kernel module we can tell the driver to accept any SFPs. |

+ | # But this tool will flip the right bit 1 to make that change permanent in the configuration bits in the EEPROM, |

Тут нужно указать список если более чем одна карта (или порт?)
x520 Unlocker
В теории это нужно что бы установить карту там, где драйвер не имеет опции отключения проверки.
Последний бит должен быть установлен 1 (в примере уже установлен, в обоих случаях )
ethtool -e enp3s0f1 offset 0x58 length 1 Offset Values ------ ------ 0x0058: fd
ethtool -e enp7s0f0 offset 0x58 length 1 Offset Values ------ ------ 0x0058: ff
Все манипуляции проводить только с 1 битом, например если было значение fe
( Бинарное 11111110
) то записать следует ff
( Бинарное 11111111
)
ethtool -E enp1s0 magic 0x10fb8086 offset 0x58 value 0xff
Магическое значение можно посмотреть так:
lspci -nn | grep 82599 03:00.0 Ethernet controller [0200]: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection [8086:10fb] (rev 01) 03:00.1 Ethernet controller [0200]: Intel Corporation 82599ES 10-Gigabit SFI/SFP+ Network Connection [8086:10fb] (rev 01)
