I'm trying to enable L2CAP Enhanced Credit Based Mode in order to pass BT qualification test GATT/SR/GAC/BI-01-C, but it seems that something is still missing. When my BT stack receives "LE L2CAP: Enhanced Credit Connection Request (0x17)" it answers with "LE L2CAP: Command Reject (0x01) / Reason: Command not understood (0x0000)"

I'm using BlueZ 5.54 and kernel '4.20.0-yocto-standard' with the following patches taken from 'bluetooth-next':
