Saeed Mahameed says:

====================
mlx5-updates-2021-04-16

This patchset introduces updates to mlx5e netdev driver.

1) Tariq refactors TLS offloads and adds resiliency against RX resync
   failures

2) Maxim reduces code duplications by unifying channels reset flow
   regardless if channels are closed or open

3) Aya Enhances TX/RX health reporters diagnostics to expose the
   internal clock time-stamping format

4) Moshe adds support for ethtool extended link state, to show the reason
   for link down
