Subject: ethtool 5.16 release / ethtool -m bug fix

Hi Michal!

Sorry to hasten but I'm wondering if there is a plan to cut the 5.16
ethtool release? Looks like there is a problem in SFP EEPROM parsing
code, at least with QSFP28s, user space always requests page 3 now.
This ends in an -EINVAL (at least for drivers not supporting the paged
mode).

By the looks of it - Ido fixed this in 6e2b32a0d0ea ("sff-8636: Request
specific pages for parsing in netlink path") but it may be too much code 
to backport so I'm thinking it's easiest for distros to move to v5.16.
