emulated sounds good but the ieee1588 doesn't sit well with me.
IEEE1588 doesn't describe tickers and external signals.
Let's leave them in the main directory? Or call it hw even if
it's not 100% accurate? In MAINTAINERS you can exclude subdir
with X:

Thanks for the suggestion. Leaving the network-oriented drivers
in the main directory and using X: in MAINTAINERS to exclude the
emulated ones makes sense to me. The layout will be adjusted in
the next version.
