I severely doubt this.  25 32-bit state variables is just way
over the top.

Don't give up so easily.  Maybe some values can be 16-bit instead
of 32-bit.

Perhaps pairs of two odd-sized values can be encoded into a single
32-bit (one is 7 bits, the other is <= 25 bits).

Get creative.

I'm going to be very much an asshole about making that blob any
bigger, because it means every single socket in the kernel will get
bigger even if they don't use your congestion control algorithm.
