[PATCH RFC next v2 0/5] net: guard SYS_RX_ETH_BUFFER with NET + required changes (ls1028a!) to make this happen

[Quentin Schulz]

Adding ls1028a to the mail subject so that maybe it triggers some filter
for maintainers/reviewers of those boards.

Follow-up to the NET->NET_LEGACY rename, where CONFIG_SYS_RX_ETH_BUFFER
was discovered[1] to be in net/Kconfig but not guarded by NET.

Move a few things around such that we can guard this symbol by NET.

It'd be nice if someone could check patch 2 works as intended on the
impacted platform(s), hence the RFC (and the ls1028a! in the mail
subject).
