[Removing Linus and Linux kernel mailing list]
@Roland,
We would like to get Cisco usNIC driver inbox in 3.13 so our customers
can 1) pick it up from Red Hat releases and 2) be able to get support from Red
Hat.

Two months have passed since the patch was submitted on the mailer and we have
incorporated all of the feedback. This code has been shipping for few months
now and it also has gone through three Cisco QA cycles. However, it is far
from finished and I'm sure it can be improved; we have pending bug fix patches.
We are happy to take further feedback from the mailer, but the requested
changes should be delayed until the 3.14 merge window.
Are there any reasons for holding off usNIC until the next merge window?
Upinder
p.s. - We have one more set of patches upcoming that support usNIC on UDP. We
would also like to get these in the 3.13 merge window if the community feedback
is incorporated by this week.
