SFP+를 로드할 수 없습니다.

CentOS7 7.5.1804를 사용하고 있습니다. Intel 82599 기반의 10gig SFP+ 카드가 있습니다. SFP를 시도하면 다음과 같은 결과를 얻습니다.

failed to load because an unsupported SFP+ or QSFP module type was detected.

커널 옵션 추가를 포함하여 온라인에서 찾은 모든 것을 시도했습니다[1].

ixgbe.allow_unsupported_sfp=1

나도 시도했다

modprobe ixgbe allow_unsupported_sfp=1

실제로 modinfo -p ixgbe를 실행하면 다음과 같은 결과가 나타납니다.

[root@codd-b01 ~]# modprobe ixgbe 
[root@codd-b01 ~]# modinfo -p ixgbe
max_vfs:Maximum number of virtual functions to allocate per physical function - default is zero and maximum value is 63 (uint)
allow_unsupported_sfp:Allow unsupported and untested SFP+ modules on 82599-based adapters (uint)
debug:Debug level (0=none,...,16=all) (int)
[root@codd-b01 ~]#

아래에서는 모듈을 제거하고 다시 로드한 후 Linux에서 SFP를 허용하지 않음을 보여주는 것을 포함하여 모든 단계를 볼 수 있습니다.

[root@codd-b01 ~]# dmesg | grep SFP

내가 찾은 최고는 [2]이지만 RHEL 구독이 없습니다.
