net: thunderbolt: Enable end-to-end flow control also in transmit

Browse source

[ Upstream commit a8065af334 ]

According to USB4 specification, if E2E flow control is disabled for
the Transmit Descriptor Ring, the Host Interface Adapter Layer shall
not require any credits to be available before transmitting a Tunneled
Packet from this Transmit Descriptor Ring, so e2e flow control should
be enabled in both directions.
