LwM2M will use the validation buffer during the write operation, to
decode the resource value before validating it (applies for resources
for which validation callback has been registered). Set this value to
the maximum expected size of the resources that need to be validated
(and thus have validation callback registered).
Setting the validation buffer size to 0 disables validation support.

after sending a message to the server. Note, that LWM2M specification
recommends this to be CoAP MAX_TRANSMIT_WAIT parameter (which
