config NET_ARCH_INCR32
bool "Architecture-specific net_incr32()"
default n
---help---
Define if you architecture provided an optimized version of
net_incr32() with prototype:
void net_incr32(FAR uint8_t *op32, uint16_t op16)
config NET_ARCH_CHKSUM
bool "Architecture-specific net_chksum()"
default n
---help---
Define if you architecture provided an optimized version of
functions with the following prototypes:
uint16_t chksum(uint16_t sum, FAR const uint8_t *data, uint16_t len)
uint16_t net_chksum(FAR uint16_t *data, uint16_t len)
uint16_t ipv4_chksum(FAR struct ipv4_hdr_s *ipv4)
uint16_t ipv4_upperlayer_chksum(FAR struct net_driver_s *dev, uint8_t proto)
uint16_t ipv6_upperlayer_chksum(FAR struct net_driver_s *dev, uint8_t proto, unsigned int iplen)
