Add link for bonw15 Ethernet

[ahoneybun]

This is needed for working Ethernet as reported and confirmed by a customer.

Why link to Intel's site, rather than download to this repo and link it there? Also don't we usually get these elsewhere?

[ahoneybun]

The org of this repo is not very clear and I guess I should just ping @crawfxrd on how he wants to do this addition.

[crawfxrd]

I think we get all the Intel drivers from the private software kits, preferably the Best Known Configuration kits.

[crawfxrd]

The Ethernet drivers in BKC are for I219 and I225-I226. They do not provider installers, just the driver files.

In that case is there a reason to not link to official Intel docs that provide the driver(s)?

[crawfxrd]

Have we had any questions about Intel Ethernet drivers for other systems?

These use I219 and would need the driver link as well:

• addw3
• darp10
• gaze16
• gaze17

[ahoneybun]

I don't believe so but I don't see a reason to not list the driver for those models in this PR or another one.
