commit 1c963e5976a812771a4f3329e340ff9f9bef4406 (HEAD)
Author: Stephen Hemminger <[email protected]>

tailq: fix name truncation
The tailq name is defined as 32 bytes, but name would be
silently truncated at 31 bytes. The function strlcpy() size
already accounts for the NUL character at the end.
Bugzilla ID: 1954
Fixes: f9acaf84e923 ("replace snprintf with strlcpy without adding extra
include")
