Subject: [PATCH net-next 0/7] net: intel: replace deprecated strncpy uses


This series aims to eliminate uses of strncpy() as it is a deprecated
interface [1] with many viable replacements available.

Predominantly, strscpy() is the go-to replacement as it guarantees
NUL-termination on the destination buffer (which strncpy does not). With
that being said, I did not identify any buffer overread problems as the
size arguments were carefully measured to leave room for trailing
NUL-bytes. Nonetheless, we should favor more robust and less ambiguous

Previously, each of these patches was sent individually at:

Consider these dead as this series is their new home :)

I found all these instances with: $ rg "strncpy\("

This series may collide in a not-so-nice way with [3]. This series can
go in after that one with a rebase. I'll send a v2 if necessary.
