[PATCH 0/3] net: Cleanups for FORTIFY_SOURCE

Hi,

In preparation for FORTIFY_SOURCE performing compile-time and run-time
field bounds checking for memcpy(), memmove(), and memset(), avoid
intentionally writing across neighboring fields.

These three changes have been living in my memcpy() series[1], but have
no external dependencies. It's probably better to have these go via
netdev.

Thanks!
