Wait in the send callback for the packet to be actually sent. After this change, only one TX packet will be handled at once. This is needed because of the way the TX packets are currently handled in L2 after this PR: #12563 This is similar to what #13167 did for the SAM GMAC on SAM E-70. Without this, packet time-stamping does not work with the current stack. This commit is minimalistic on purpose to make it easily revertible when the network stack is able to properly handle DMA drivers for TX packets again.
