[ale] OT: Ethernet wiring

[DJ-Pfulio]

CAT6 is nice when you need extra shielding, but won't ever do more than
1Gbps.  CAT5e has double the requirement to provide 1Gbps.  I bought a
bunch of CAT6, thinking it would support 10G ethernet over copper. That
never happened and doesn't look likely today.

So ... if you don't have a reason to have more shielding or thicker
cables, CAT5e (not just CAT5) is absolutely fine. Save the money.

Can anyone correct me?
