| Subject: net: ieee802154: mcr20a: Fix lifs/sifs periods |
| |
| From: Miquel Raynal <miquel.raynal@bootlin.com> |
| |
| commit d753c4004820a888ec007dd88b271fa9c3172c5c upstream. |
| |
| These periods are expressed in time units (microseconds) while 40 and 12 |
| are the number of symbol durations these periods will last. We need to |
| multiply them both with phy->symbol_duration in order to get these |
| values in microseconds. |
