Subject: [PATCH net 0/2] net: ipa: HOLB register write fixes

This small series fixes two recently identified bugs related to the
way two registers must be written.  The registers define whether and
when to drop packets if a head-of-line blocking condition is
encountered.  The "enable" (dropping packets) register must be
written twice for newer versions of hardware.  And the timer
register must not be written while dropping is enabled.
