6.6-stable review patch. If anyone has any objections, please let me know.

commit 97eb5d51b4a584a60e5d096bdb6b33edc9f50d8d upstream.
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.
