I've noticed that SmartMesh support is curiously lacking from the R500/R600 data sheets. Am I reading too far between the lines that unlike the T300's and R700's, the R500/R600 will not support meshing?
Maybe, but probably just. The powers that be have decided to rename what would have been "9.9.1" maintenance release to "9.10" digits. This is a deviation from previous numbering schemes.
