Seems outdated comment about ReceivePath and channel

[dinayuil]

lorawan/helper/lora-phy-helper.cc

Lines 78 to 82 in f309062

	// For now, assume that the PHY will listen to the default EU channels
	// with this ReceivePath configuration:
	// 3 ReceivePaths on 868.1 MHz
	// 3 ReceivePaths on 868.3 MHz
	// 2 ReceivePaths on 868.5 MHz

Are these comments still relevant? From the code I don't see the reception path being related with a specific frequency.
I also did a small test, by sending 4 packet at the same time on the same 868.1 frequency, SF 7-10. All packets were received by the gateway.
So, I think the comments are outdated?
Thanks in advance!

Yes, the comments are outdated. They come from an old version of the gateway model that was changed some years ago. I'll leave this issue open as a reminder to remove/update them.
