| Subject: net: ieee802154: ca8210: Fix lifs/sifs periods |
| |
| From: Miquel Raynal <miquel.raynal@bootlin.com> |
| |
| commit bdc120a2bcd834e571ce4115aaddf71ab34495de 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 the symbol_duration in order to get these |
| values in microseconds. |
