wireless-regdb: Update regulatory rules for canada on 5GHz

[Eric Sellman]

I would like to submit a correction to the wireless regulatory database for canada. 

https://ised-isde.canada.ca/site/spectrum-management-telecommunications/en/devices-and-equipment/radio-equipment-standards/radio-standards-specifications-rss/rss-247-digital-transmission-systems-dtss-frequency-hopping-systems-fhss-and-licence-exempt-local#s6

"6.2.3 Frequency bands 5470-5600 MHz and5650-5725 MHz

Until further notice, devices subject to this section shall not be capable of transmitting in the band 5600-5650 MHz. This restriction is for the protection of Environment Canada’s weather radars operating in this band."

https://git.kernel.org/pub/scm/linux/kernel/git/sforshee/wireless-regdb.git/tree/db.txt#n326

Lines 330 and 331 have frequencies 5600mhz to 5650mhz and therefore need to be modified to have those frequencies removed.

My apologies but I have made a mistake.

My previous submission about Canada is invalid. The weather frequency range has already been avoided.

Here is the correct information I meant to share with you.

https://www.ic.gc.ca/eic/site/smt-gst.nsf/eng/sf10971.html#s6

"Devices with occupied bandwidths which overlap different bands shall comply with all operational requirements for each band."

https://semfionetworks.com/blog/5ghz-regulations-in-canada-2018-update/

Canada still permits the lower 5ghz frequencies to be used for VHT 160. But it's missing according to the information for the Canadian profile in line 326

https://git.kernel.org/pub/scm/linux/kernel/git/sforshee/wireless-regdb.git/tree/db.txt#n326.

And I wanted to mention that for 5150 - 5250 on line 328, the transmit power has been increased to 1 watt or "30 dBm" according to this document here.

Just for the record, as we discussed for the US rules, we can't set the
max bandwidth for a range to a value larger than the range itself or the
kernel will reject the database. However, it looks like with AUTO_BW the
kernel will allow larger bandwidths with adjacent channels.

I see a limit of 200 mW for 5150-5250 MHz. If I'm missing it, can you
please tell me which section specifies a max EIRP of 30 dBm?

Thanks,
Seth
