Subject: [PATCH V3 net-next 0/8] ENA driver new features

From: Arthur Kiyanovski <akiyano@...zon.com>

V4 changes:
-----------
Add smp_rmb() to "net: ena: avoid unnecessary rearming of interrupt
vector when busy-polling" to adhere to the linux kernel memory model,
and update the commit message accordingly.

V3 changes:
-----------
1. Add "net: ena: enable support of rss hash key and function
   changes" patch again, with more explanations why it should
   be in net-next in commit message.
2. Add synchronization considerations to "net: ena: avoid unnecessary
   rearming of interrupt vector when busy-polling"


V2 changes:
-----------
1. Update commit messages of 2 patches to be more verbose.
2. Remove "net: ena: enable support of rss hash key and function
   changes" patch. Will be resubmitted net.


V1 cover letter:
----------------
This patchset contains performance improvements, support for new devices
and functionality:

1. Support for upcoming ENA devices
2. Avoid unnecessary IRQ unmasking in busy poll to reduce interrupt rate
3. Enabling device support for RSS function and key manipulation
4. Support for NIC-based traffic mirroring (SPAN port)
5. Additional PCI device ID
6. Cosmetic changes
