I have submitted this patch set yesterday. It contains 14 patches. But 
only 2 of those patches were received by LKML only the cover letter and 
the 13th patch. 
(https://lore.kernel.org/linux-usb/cover.1617782102.git.Arthur.Petrosyan@synopsys.com/T/#t)

I checked here at Synopsys, Minas did receive all the patches as his 
email is in To list. Could this be an issue of vger.kernel.org mailing 
server?

Because I checked every local possibility that could result to such 
behavior. The patch 13 which was received by LKML has the similar 
content as the other patches.

The mailing tool that was used is ssmtp, checked all the configurations 
everything is fine.

Could you please suggest what should I do in this situation?

Regards,
Artur
