What now when we're [almost] out of ADVERTISED bits?

What now when we're [almost] out of ADVERTISED bits?

[Yuval Mintz]

[I suspect there was probably some discussion over this,
but I couldn't find it; References would be welcome]

So it appears we're almost out of bits for new advertised speeds;
I'm currently looking at adding 100g.

Assuming we want [and we do want] to have those in the `supported',
`advertising' and `lp_advertising' fields, the 2 reserve fields in
ethtool_cmd would not be sufficient [unless we break them into 4 u16].
Or are we planning something more generic than this for future bits?

Following with a slightly [but related] topic, what's our policy for
non-finalized standards? Specifically, for 25Gb and 50Gb?

Thanks,
Yuval

there was a work by David Decotigny that should have solved the out of
bits problem here [1]. Maybe it should be revived.

A repost would strongly facilitate that.

Just if anyone ever thinks something is being ignored, just don't
even use your brain, simply repost it again.

David, are you going to re-post? Or do you want me to take over this one?

Thanks,
