Title:
  bnx2x: Add FW 7.13.21.0

Status in linux-firmware package in Ubuntu:
  Fix Released
Status in linux-firmware source package in Focal:
  Fix Released
Status in linux-firmware source package in Impish:
  Won't Fix
Status in linux-firmware source package in Jammy:
  Fix Released

Bug description:
  [Impact]

   * There is new version of bnx2x firmware

   * oem-5.14 and hwe-5.15 kernels use that one; and when not found
  fallback to previous version of firmware.

  [Test Plan]

   * sudo apt install initramfs-tools
   * echo bnx2x | sudo tee -a /etc/initramfs-tools/modules
   * sudo apt install linux-oem-20.04 linux-generic-hwe-20.04-edge

  With current linux-firmware the above results in:

  update-initramfs: Generating /boot/initrd.img-5.15.0-22-generic
  W: Possible missing firmware /lib/firmware/bnx2x/bnx2x-e2-7.13.21.0.fw for 
module bnx2x
  W: Possible missing firmware /lib/firmware/bnx2x/bnx2x-e1h-7.13.21.0.fw for 
module bnx2x
  W: Possible missing firmware /lib/firmware/bnx2x/bnx2x-e1-7.13.21.0.fw for 
module bnx2x

  with updated linux-firmware no lines of "Possible missing firmware"
  should appear.

  [Where problems could occur]

   * v21 firmware version is backwards compatible with v15 firmware
  previously used, but includes bugfixes. It may result in different NIC
  behavior.

  [Other Info]

   * The v21 firmware is already present in Jammy
   * The kernels that use v21 firmware are not going to be shipped in Impish
   * The kernels that use v21 firmware will be available/used in Focal

  Upstream changelog for the blobs:

  New firmware v7.13.21.0 along with below fixes/enhancements (which
  were also part of 7.13.20.0) maintains backward compatibility as well,
  so that driver can be worked with both the new firmware and an older
  firmware.

  - Support direct invalidation of FP HSI Ver per function ID, required for
    invalidating FP HSI Ver prior to each VF start, as there is no VF start
  - BRB parity error detection support for the driver
  - Fix the FCOE underrun flow
  - Fix PSOD during FCoE BFS over the NIC ports after preboot driver
