Throughput increased from 1.30Gbit/s to 1.60Gbit/s average on my dev laptop, though this is likely because we now use a dedicated task for reading and writing, which allows parallel reads and writes. Signed-off-by: Lee Smet <lee.smet@hotmail.com>

Adds backpressure compared to the unbounded channel. Prevents the TUN reads from outpacing the Dataplane operation, which would lead to increased latency and potential OOM. Now the data will be accumulated in kernel buffers, and eventually get dropped. Signed-off-by: Lee Smet <lee.smet@hotmail.com>

Rather than doing an all or nothing coallesce on the received packets This also fixes an issue with GRO'd packet csum computation, especially on UDP Signed-off-by: Lee Smet <lee.smet@hotmail.com>
Improves GRO performance by doing a batch of decryptions instead of decrypting individual packets to then send them to the TUN interface Signed-off-by: Lee Smet <lee.smet@hotmail.com>
This should slightly reduce the amount of syscalls needed when sending packets to/receiving packets from peers under heavy load. Signed-off-by: Lee Smet <lee.smet@hotmail.com>
