Description
The max UDP message size is currently hardcoded to 9012. We would like to increase it, since our max workload message size is greater.
Quick fix:
export CHISEL_UDP_MAX_SIZE=12000
share\tunnel\tunnel_out_ssh_udp.go:80
share\tunnel\tunnel_in_proxy_udp.go:83
const maxMTU = settings.EnvInt("UDP_MAX_SIZE", 9012)
or command line param e.g. --udp-max-size 12000

Research direction
Start with share/tunnel/tunnel_out_ssh_udp.go:80 and share/tunnel/tunnel_in_proxy_udp.go:83, then inspect settings.EnvInt and the existing UDP_MAX_SIZE handling. Determine the supported configuration mechanism and verify that a larger configured value is applied consistently to both UDP paths.
