True. However, you can create a "normal" driver table entry for an
Ethernet driver if you want to.
Then you can have an init function called exactly once at system
You can also then use use cyg_io_read(), cyg_io_write(),
cyg_io_set_config(), cyg_io_get_config() etc. for whatever you want.
I've done that in the past for a number of Ethernet drivers so that
user application can read/write raw MAC-level packets for certain
proprietary Ethernet protocols. [The eCos network stacks didn't used
to provide any mechanism for that]. We also use the normal cyg_io API
to allow application code to configure and uery a variety of features
in the Ethernet controller hardware that the normal network stacks are
not aware of and for which they provide no API.
