Title: INTERRUPT LEVEL PROCESSING IN ETHERNET DRIVERS Title: IPv6 REQUIRES ADDRESS FILTER SUPPORT
Description: Too many Ethernet drivers do interrupt-level processing with Description: IPv6 requires that the Ethernet driver support NuttX address
the network stack. The network stack supports either interrupt filter interfaces. Several Ethernet drivers do support there,
level processing or normal task level processing (depending on however. Others support the address filtering interfaces but
CONFIG_NET_NOINTS). This is really a very bad use of CPU have never been verifed:
resources; All of the network stack processing should be
modified to use a work queue (and, all use of CONFIG_NET_NOINTS=n
should be eliminated). This applies to many Ethernet drivers:
