Fedora has a newer upstream version, but they have a patch related to this:
https://src.fedoraproject.org/rpms/fcoe-utils/blob/master/f/fcoe-utils-ggc7-fmt-truc-err.patch
I have modified it to apply to the Debian package.

However, even after applying the attached patch, the package FTBFS:

fcping.c: In function 'fp_find_hba':
fcping.c:591:9: error: '%s' directive output may be truncated writing up to 255 bytes into a region of size 61 [-Werror=format-truncation=]
     "fc_%s", port_attrs.OSDeviceName);
         ^~   ~~~~~~~~~~
