config ETH_NXP_S32_RX_THREAD_PRIO
int "RX thread priority"
default 2
help
RX thread priority. RX thread is a cooperative thread.
config ETH_NXP_S32_RX_THREAD_STACK_SIZE
int "RX thread stack size"
default 1500
help
RX thread stack size.
config ETH_NXP_S32_RX_BUDGET
int "RX thread budget"
default 128
range 1 1024
help
The budget parameter places a limit on the amount of work the driver may
do in the RX thread before yielding the processor, in case there is more
work to do. This is to prevent the RX thread to starve other threads. Each
received frame counts as one unit of work.
config ETH_NXP_S32_TX_RING_LEN
int "TX ring length"
default 64
range 8 256
help
Length of the TX ring. The value must be a multiple of 8.
config ETH_NXP_S32_TX_RING_BUF_SIZE
int "TX ring data buffer size"
default 1536
range 64 1536
help
Size, in bytes, of the TX data buffer. The size must be big enough to
store one complete Ethernet frame, and be a multiple of 8.
config ETH_NXP_S32_RX_RING_LEN
int "RX ring length"
default 64
range 8 256
help
Length of the RX ring. The value must be a multiple of 8.
config ETH_NXP_S32_RX_RING_BUF_SIZE
int "RX ring data buffer size"

help
Size, in bytes, of the RX data buffer. The size must be big enough to
store one complete Ethernet frame, and be a multiple of 8.
config ETH_NXP_S32_RX_IRQ_PACKET_THRESHOLD
int "RX interrupt coalescing packet threshold"
default 32
range 1 511
help
RX interrupt coalescing packet threshold. This values determines the
minimum number of packets received before raising an interrupt.
config ETH_NXP_S32_RX_IRQ_TIMER_THRESHOLD
int "RX interrupt coalescing timer threshold"
default 60000
range 1 4294967295
help
RX interrupt coalescing timer threshold, in units of NETC clock cycles.
This value determines the maximum amount of time allowed between a first
received packet until RX interrupt coalescing packet threshold is reached.
If the timer expires before the threshold is reached, an interrupt is
raised.
config ETH_NXP_S32_MAC_FILTER_TABLE_SIZE
int "MAC filter hash table size"
default 8
range 8 128
help
Maximum number of entries supported in the MAC filter hash table.
config ETH_NXP_S32_PSI_INIT_PRIORITY
int
default 60
help
PSI initialization priority. It must be lower than VSI priority.
config ETH_NXP_S32_VSI_INIT_PRIORITY
int
default 61
help
VSI initialization priority. It must be bigger than PSI priority
and lower than CONFIG_NET_INIT_PRIO, so that it can start after the PSI
but before the networking sub-system.
