thanks krzk!

FTR, to support RTL8153B (HW ID 0x6010), the follow patch series to
bring r8152 v1.09.9 driver from 4.14 kernel.org to 3 (of 5) older
Chrome OS kernels:

3.14: https://chromium-review.googlesource.com/q/topic:%22update_r8152-3.14%22+(status:open%20OR%20status:merged)
3.18: https://chromium-review.googlesource.com/q/topic:%2522update-r8152-3.18%2522+(status:open+OR+status:merged)
4.4: https://chromium-review.googlesource.com/q/topic:%2522update_r8152-4.4%2522+(status:open+OR+status:merged)

caveat: These series are not suitable directly for kernel.org
submission (extraneous stuff in the commit messages, order is
different). Using the original SHA1 (in each commit message), this can
all be fixed up by hand/simple scripts.

cheers,
grant
