Re: [ipwave] About OCB patch for ath10k driver on linux

[Alexandre Petrescu <[e-mail]>]

I dont know whether the patch files and howto for ath10k were received 
by participants or not.  Some have not; I sent them the files in private.

The patch files might be missing from my email because I think it might 
be that the email system 'mailman' filters (cuts) the attachments.

To avoid that misunderstanding, one should use a repository.

A repository of appropriate profile could be at 
https://its.dot.gov/code/ « ITS Code Hub »

One could try to make an account and upload the files of ath10k to that 
repository, and then publish here the link.

Other questions I have about that dot.gov site is whether or not it 
supports IPv6 access, but that is accessory.  github.com doesnt support 
IPv6 either.

Another question one might raise before putting the files there is about 
that being in a country and not in another country.  At this time I do 
not mind about that, because the technology of this code is to be used 
in any country, like the Internet.
