axe(4) and Plugable USB2-E1000 (or: general USB Ethernet advice)

[Rotate 13]

I am looking for a USB ethernet adapter which works with very stable
driver in FreeBSD.  To effect this end, I went through section 4 man
pages, and made list of drivers for USB ethernet chips.  The problem
is, many are apparently not widely available or in current production
- but I found ASIX AX88178 and ASIX AX88772 (axe(4)) in various
devices from http://plugable.com/ .  I am mostly interested in ASIX
AX88178 due to faster speed (albeit limited by USB2 speed).

My questions:

	* Does anybody have good or bad experience with Plugable USB2-E1000
(ASIX AX88178) in FreeBSD?  Stability is utmost concern, followed by
performance.  I note, Amazon.com page for product says also it has
Realtek RTL8211CL PHY - I do not understand why, and cannot find info
explaining this.  Is perhaps slower USB2-E100 with ASIX AX88772 more
compatible?

	* Any advice on rock-solid usage of USB Ethernet in FreeBSD, and
pointers to other products will be much appreciated.

Thanks in advance.
