Ошибка ixgbe failed to load because an unsupported SFP+ module type was detected
x520
- файл
/etc/default/grub.d/60_custom.cfg
GRUB_CMDLINE_LINUX="$GRUB_CMDLINE_LINUX ixgbe.allow_unsupported_sfp=1"
Или если более чем одна карта - ixgbe.allow_unsupported_sfp=1,1,1,1
- Файл
/etc/modprobe.d/ixgbe.conf
options ixgbe allow_unsupported_sfp=1,1,1,1
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)
[8086:10fb] --> 0x 10fb 8086
Что бы не возиться руками все те же манипуляции можно сделать скриптом

# Simple Intel x520 EEPROM patcher
# Modifies the EEPROM to unlock the card for non-intel branded SFP modules.

#
# Quick explanation of what's going on:
# 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,
# thus making kernel module parameters unnecessary.
