Known Issues with Solarflare driver/firmware
--------------------------------------------
SF-119015-KI / Issue 72914:
 ~ [SFN7xxx series firmware only].
   There is an issue when using MCFW where a transmit queue using TSO may lockup
   and cause a NETDEV watchdog.
 ~ In the default configuration of "pf-count=1" (where there is no NIC
   partitioning) the NETDEV watchdog will occur on TX queue >=31, this will
   only be used if there are more than 32 logical CPUs in the machine, or if the
   "rss_cpus" module parameter is explicitly set.
 ~ As a workaround please set the module parameter to at most "rss_cpus=31".
 ~ As a fix please update adapter firmware using the "sfutils" package from
   https://support.solarflare.com to MCFW >= v6.2.7.1000

Issue 50868:
  ~ If using a SFN7142Q adapter with adapter firmware v4.1.0.6742 and running
    sfupdate, after the update the two network interfaces from the second QSFP+
    port will be in a disabled state. Please reload the driver to correct this.
    This issue has been resolved in adapter firmware >=v4.1.1.1022.
