[PATCH v2 net-next 0/5] ENA driver changes May 2024

[darinzon]

From: David Arinzon <darinzon@amazon.com>

This patchset contains several misc and minor
changes to the ENA driver.

Changes from v1:
- Removed interrupt moderation hint from the
  patchset. The change is moved back to
  development state and will be released as
  part of a different patchset in the future. 

David Arinzon (5):
  net: ena: Add a counter for driver's reset failures
  net: ena: Reduce holes in ena_com structures
  net: ena: Add validation for completion descriptors consistency
  net: ena: Changes around strscpy calls
  net: ena: Change initial rx_usec interval

[PATCH v2 net-next 1/5] net: ena: Add a counter for driver's reset failures

[darinzon]

From: David Arinzon <darinzon@amazon.com>

This patch adds a counter to the ena_adapter struct in
order to keep track of reset failures.
The counter is incremented every time either ena_restore_device()
or ena_destroy_device() fail.

[PATCH v2 net-next 3/5] net: ena: Add validation for completion descriptors consistency

[darinzon]

From: David Arinzon <darinzon@amazon.com>

Validate that `first` flag is set only for the first
descriptor in multi-buffer packets.
In case of an invalid descriptor, a reset will occur.
A new reset reason for RX data corruption has been added.

[PATCH v2 net-next 4/5] net: ena: Changes around strscpy calls

[darinzon]

From: David Arinzon <darinzon@amazon.com>

strscpy copies as much of the string as possible,
meaning that the destination string will be truncated
in case of no space. As this is a non-critical error in
our case, adding a debug level print for indication.

This patch also removes a -1 which was added to ensure
enough space for NUL, but strscpy destination string is
guaranteed to be NUL-terminted, therefore, the -1 is
not needed.
