config NET_PPP_DRV_NAME
string "PPP Driver name"
default "ppp"
help
This option sets the driver name
config NET_PPP_MTU_MRU
int "PPP MTU and MRU"
default 1500
help
This options sets MTU and MRU for PPP link.
config NET_PPP_UART_BUF_LEN
int "Buffer length when reading from UART"
default 8
help
This options sets the size of the UART buffer where data
is being read to.
config NET_PPP_RINGBUF_SIZE
int "PPP ring buffer size"
default 256
help
PPP ring buffer size when passing data from RX ISR to worker
thread that will pass the data to IP stack.
config NET_PPP_RX_STACK_SIZE
int "Size of the stack allocated for receiving data from modem"
default 768
help
Sets the stack size which will be used by the PPP RX workqueue.
config NET_PPP_RX_PRIORITY
int "RX workqueue thread priority"
default 7
help
Sets the priority of the RX workqueue thread.
config NET_PPP_VERIFY_FCS
bool "Verify that received FCS is valid"
default y
help
If you have a reliable link, then it might make sense
to disable this as it takes some time to verify the received
packet.
config PPP_MAC_ADDR
string "MAC address for the interface"
help
Specify a MAC address for the PPP interface in the form of
six hex 8-bit chars separated by colons (e.g.:
aa:33:cc:22:e2:c0). The default is an empty string, which
means the code will make 00:00:5E:00:53:XX, where XX will be
random.
config PPP_CLIENT_CLIENTSERVER
bool "Reply to the request CLIENT with CLIENTSERVER"
help
This is only necessary if a ppp connection should be
established with a Microsoft Windows PC.
config PPP_NET_IF_NO_AUTO_START

help
This option allows user to disable autostarting of the PPP interface
immediately after initialization.

int "Buffer length from where the write to async UART is done"
default 2048
help
This options sets the size of the UART TX buffer where data
is being written from to UART.

testing, should not be enabled for normal applications
