Subject: [PATCH net-next v3 2/6] ice: Remove and replace ice speed defines with ethtool.h versions
From: Brett Creeley <brett.creeley@...el.com>
The driver is currently using ICE_LINK_SPEED_* defines that mirror what
ethtool.h defines, with one exception ICE_LINK_SPEED_UNKNOWN.
This issue is fixed by the following changes:
1. replace ICE_LINK_SPEED_UNKNOWN with 0 because SPEED_UNKNOWN in
ethtool.h is "-1" and that doesn't match the driver's expected behavior
2. transform ICE_LINK_SPEED_*MBPS to SPEED_* using static tables and
fls()-1 to convert from BIT() to an index in a table.
