tuexen discussed how to mitigate blackhole detection problems
tuexen@ has a review to ensure we don't do blackhole detection once we are at the minimum value D24308; committed
Discussion on what should trigger blackhole detection – full size? Or, even smaller messages which are above our min MTU? For at least IPv6, min MTU makes sense.
Otherwise, tuexen@'s plan remains unchanged.
BBR and RACK needs some modifcation
Discussion of D24237: rscheff@ changed both the in-order and out-of-order data path so we call sorwakeup_locked() [when necessary] after the SACK blocks are updated. rrs@ will review.
