The SYSCTL_NODE macro defines a list that stores all child-elements of that node. If there's no SYSCTL_DECL macro anywhere else, there's no reason why it shouldn't be static.

/*
|
|
* The Pegasus chip uses four USB "endpoints" to provide 10/100 ethernet
|
|
* support: the control endpoint for reading/writing registers, burst
|
|
* read endpoint for packet reception, burst write for packet transmission
|
|
* and one for "interrupts." The chip uses the same RX filter scheme
|
|
* as the other ADMtek ethernet parts: one perfect filter entry for the
|
|
* the station address and a 64-bit multicast hash table. The chip supports
|
|
* both MII and HomePNA attachments.
|
|
*
|
|
* Since the maximum data transfer speed of USB is supposed to be 12Mbps,
|
|
* you're never really going to get 100Mbps speeds from this device. I
|
|
* think the idea is to allow the device to connect to 10 or 100Mbps
|
|
* networks, not necessarily to provide 100Mbps performance. Also, since
|
|
* the controller uses an external PHY chip, it's possible that board
|
|
* designers might simply choose a 10Mbps PHY.
|
|
*
|
|
* Registers are accessed using uether_do_request(). Packet
|
|
* transfers are done using usbd_transfer() and friends.
