[PATCH v4 078/103] net/ice/base: support E830 in Topology AQ command

[Anatoly Burakov]

From: Dan Nowlin <dan.nowlin at intel.com>

In E830, regarding the Get Tx Topology AQ command, there is a change in
the way that the RD bit must be set. For E830, the RD bit must be
cleared. Setting the RD bit for the E830 device was causing the Get Tx
Topology command to fail.

Fix it to clear RD bit for E830 device.
