[...] Status report: nve(4) can handle long frames (thanks to Pyun YongHyeon for testing it), so now the driver sets the respective bit in if_capenable. tl(4) remains a grey area. If somebody needs to run VLANs over tl(4) and makes sure it can handle long frames in default mode (at least rumours say so), I'll be glad to reflect that capability in the driver. -- Yar
