O-Subject: [RHEL-8.2 PATCH 16/78] bnxt_en: read the clause type from the PHY ID
Bugzilla: 1724766
RH-Acked-by: John Linville <linville@redhat.com>
RH-Acked-by: Jarod Wilson <jarod@redhat.com>

Currently driver hard code Clause 45 based on speed supported by the
PHY. Instead read the clause type from the PHY ID provided as input
to the mdio ioctl.

Fixes: 0ca12be99667 ("bnxt_en: Add support for mdio read/write to external PHY")
