39 | * The capability mask is a set of bits, one for each optional feature |
| 40 | * supported. The capability numbers for transforms are set in the | |
| 41 | * configuration (and should correspond between the two sites), although | |
| 42 | * there are sensible defaults. | |
| 5b5f297f | 43 | * |
| 3dc839ce MW |
44 | * Advertising a nonzero capability mask promises that the receiver |
| 45 | * understands LABEL_MSG3BIS messages, which contain an additional byte | |
| 46 | * specifying the transform capability number actually chosen by the MSG3 | |
| 47 | * sender. | |
| 5b5f297f IJ |
48 | * |
| 49 | * Aside from that, an empty bitmask is treated the same as | |
| 92cc0bca | 50 | * 1u<<CAPAB_BIT_ANCIENTTRANSFORM |
