Subject: [PATCH] net: sfp-bus: fix SFP mode detect from bitrate
|
|
|
|
The referenced commit moved the setting of the Autoneg and pause bits
|
|
early in sfp_parse_support(). However, we check whether the modes are
|
|
empty before using the bitrate to set some modes. Setting these bits
|
|
so early causes that test to always be false, preventing this working,
|
|
and thus some modules that used to work no longer do.
|
|
|
|
Move them just before the call to the quirk.
|
|
|
