Todo List

Global dhcp_rx_options_given [DHCP_OPTION_IDX_MAX]

: move this into struct dhcp?

Global dhcp_rx_options_val [DHCP_OPTION_IDX_MAX]

: move this into struct dhcp?

Global do_listen (struct api_msg_msg *msg)

: should we drain the recvmbox here?

Global IP_REASS_CHECK_OVERLAP

: work with IP header options

Global LWIP_NETIF_TX_SINGLE_PBUF

: TCP and IP-frag do not work with this, yet:

Global netconn_is_nonblocking (conn)

: write/send is missing)

Global netconn_set_nonblocking (conn, val)

: write/send is missing)

Global pll_wait_for_lock (unsigned int pll_id)

Use a timeout to avoid waiting forever and hanging the system

Global sysclk_get_cpu_hz (void)

This function assumes that the CPU always runs at the system clock frequency. We want to support at least two more scenarios: Fixed CPU/bus clock dividers (config symbols) and dynamic CPU/bus clock dividers (which may change at run time). Ditto for all the bus clocks.

Global sysclk_get_main_hz (void)

This function assumes that the main clock source never changes once it's been set up, and that PLL0 always runs at the compile-time configured default rate. While this is probably the most common configuration, which we want to support as a special case for performance reasons, we will at some point need to support more dynamic setups as well.
