Why is the HPS EMAC Interface splitter emac_tx_reset input associated with the emac_gtx_clk?

The emac_rx_reset is associated with the emac_rx_clk as one would expect, so why is the tx_reset not associated with the tx_clk? I traced it through the code and it is not clear why it would be like this.

In the altera_hps_emac_interface_splitter_hw.tcl file:

 

 

# connection point emac_tx_reset

add_interface emac_tx_reset reset end

set_interface_property emac_tx_reset associatedClock emac_gtx_clk

set_interface_property emac_tx_reset synchronousEdges DEASSERT

set_interface_property emac_tx_reset ENABLED true

 

add_interface_port emac_tx_reset rst_tx_n_o reset_n Input 1
