managed by enabling and disabling interrupts.
CONFIG_NET_MULTIBUFFER - Traditionally, uIP has used a single buffer
for all incoming and outgoing traffic. If this configuration is
selected, then the driver can manage multiple I/O buffers and can,
for example, be filling one input buffer while sending another
output buffer. Or, as another example, the driver may support
queuing of concurrent input/ouput and output transfers for better
performance.
CONFIG_NET_IPv6 - Build in support for IPv6

SLIP Driver. SLIP supports point-to-point IP communications over a serial
port. The default data link layer for uIP is Ethernet. If CONFIG_NET_SLIP
is defined in the NuttX configuration file, then SLIP will be supported.
The basic differences between the SLIP and Ethernet configurations is that
when SLIP is selected:
* The link level header (that comes before the IP header) is omitted.
* All MAC address processing is suppressed.
* ARP is disabled.
If CONFIG_NET_SLIP is not selected, then Ethernet will be used (there is
no need to define anything special in the configuration file to use
Ethernet -- it is the default).
CONFIG_NET_SLIP -- Enables building of the SLIP driver. SLIP requires
at least one IP protocols selected and the following additional
network settings: CONFIG_NET_NOINTS and CONFIG_NET_MULTIBUFFER.
CONFIG_NET_BUFSIZE *must* be set to 296. Other optional configuration
settings that affect the SLIP driver: CONFIG_NET_STATISTICS.
Default: Ethernet
If SLIP is selected, then the following SLIP options are available:
CONFIG_CLIP_NINTERFACES -- Selects the number of physical SLIP
interfaces to support. Default: 1
CONFIG_SLIP_STACKSIZE -- Select the stack size of the SLIP RX and
TX tasks. Default: 2048
CONFIG_SLIP_DEFPRIO - The priority of the SLIP RX and TX tasks.
Default: 128
UIP Network Utilities
CONFIG_NET_DHCP_LIGHT - Reduces size of DHCP
CONFIG_NET_RESOLV_ENTRIES - Number of resolver entries
