The flag use_avx2 and use_avx512 are defined as local variables, they
will not be aware by the secondary process, then wrong data path is
selected. Fix the issue by moving them into struct ice_adapter.
Fixes: ae60d3c9b227 ("net/ice: support Rx AVX2 vector")
Fixes: 2d5f6953d56d ("net/ice: support vector AVX2 in Tx")
Fixes: 7f85d5ebcfe1 ("net/ice: add AVX512 vector path")

Hi,
Is this tested on VFs? I saw crash on both PF as well as VF, on 20.11.1,
but did not see PF crash on 20.11.3,
I'm seeing a crash on the secondary process when it receives packet on the
VF, but PF doesn't crash now on 20.11.3
So I suspect this is the patch which is fixing the issue on ICE secondary
process crash on PF.
Thanks & Regards,
Navin Srinivas

Hi Srinivas:
This is the fix for PF driver only, for VF we have a separated fix and it is not be captured in 20.11.3, but I saw the patches are already merged in stable tree.
You can try with latest 20.11.4-rc1, or wait for 20.11.4 LTS.
Regards
Qi

Subject: Re: [dpdk-dev] [PATCH] net/ice: fix wrong data path selection in secondary process
Hi,
Is this tested on VFs? I saw crash on both PF as well as VF, on 20.11.1, but did not see PF crash on 20.11.3,
I'm seeing a crash on the secondary process when it receives packet on the VF, but PF doesn't crash now on 20.11.3
So I suspect this is the patch which is fixing the issue on ICE secondary process crash on PF.
Thanks & Regards,
Navin Srinivas

Thanks, I noticed it in the release and took the LTS version.
I do not see the previously noticed VF crash now on 20.11.4

The flag use_avx2 and use_avx512 are defined as local variables, they
will not be aware by the secondary process, then wrong data path is
selected. Fix the issue by moving them into struct ice_adapter.
Fixes: ae60d3c9b227 ("net/ice: support Rx AVX2 vector")
Fixes: 2d5f6953d56d ("net/ice: support vector AVX2 in Tx")
Fixes: 7f85d5ebcfe1 ("net/ice: add AVX512 vector path")
Cc: stable@dpdk.org
