Hi,

The input_buffer in struct jsonrpc was recently increased to 4k [ 
https://github.com/openvswitch/ovs/commit/ea5c1ba0e3b899b8b6684f23a44bbfd4331815ee 
]

Years ago there was a change [ 
https://github.com/openvswitch/ovs/commit/3a4548cfb2fb7e7344618f449ab9bf651ef83e6b 
] to limit how much cpu jsonrpc_recv() could take before yielding back 
to its caller.  Should the value of 50 be adjusted down to compensate or 
is this no longer a problem?

Thanks,
MikeC
