If anyone has any objections, please let me know. ------------------ From: Ilan Peer [ Upstream commit 407879b690ba3a6bf29be896d02dad63463bd1c0 ] The IEEE P802.11-REVmd D1.0 specification updated the SAE authentication timeout to be 2000 milliseconds (see dot11RSNASAERetransPeriod). Update the SAE timeout setting accordingly. While at it, reduce some code duplication in the timeout configuration.
