Hi, Xiao

It's better to have a cover letter for a patch series that contains more than
1 patches, where you can have an overall description of the patchset.

I suggest to describe more details (dereference after null check) about the
issue other than just say general coverity issue.

Minor nit, if i == nb_bufs, above assignment is  meaningless, suggest to move
it after i == nb_bufs check although it doesn't affect the functionality. 
I think it applies for the rest of patches too.

Thanks,
Xiaolong

This patch fixes (dereference after null check) coverity issue.
The address of first segmented packets was not set correctly during
reassembling packets which led to this issue.

Coverity issue: 343422

You can add below alias section to you git config file to create proper fix tag conveniently.

[alias]
        fixline = log -1 --abbrev=12 --format='Fixes: %h (\"%s\")%nCc: %ae'
