I see definitions for these in sdk/src/quic.rs. Can you add comments about why new definitions are needed?

The ones in sdk are used for tpu, which has very different properties than repair. In particular tpu packets are only forwarded to the upcoming leaders which we know in advance who they are, it is a uni-directional traffic, and has a very different load and latency tolerance. Repair is bi-directional request-response, peers are randomly sampled, etc.
I pretty much rather not to reuse the same parameters at this stage until this code is stable and repair over quic protocol is fully rolled out over mainnet. Until then reusing same parameters can introduce regressions on one protocol while trying to optimize another protocol.

I think just add some code comments on the reasoning will help.

Comment this to disable datagrams?

QUIC connections may timeout due to infrequent repair requests. The commit configures keep_alive_interval and max_idle_timeout to avoid timeouts. (cherry picked from commit 3ac2507)
