Subject: [PATCH] Adjust timeout LE

The hci_send_req 100ms timeout is not enough when the chip is in deep
sleep.
This patch increases it to 1000ms.

I do agree Arun, I will change the code as you suggest.

Shouldn't the to parameter be passed to hci_le_set_scan_enable(...) rather than hard-coding it and passing it to hci_send_req(as 1000)?
I see that as the logical way for all hci_* functions in hci.c that eventually call hci_send_req(). hci_le_set_scan_parameters and few others yet don't have to as input argument and should be patched suitably ...
