Description
In the function DrvEddReceiveCbk() the UDP checksum is calculated in order to varify the checksum of the received frame.
In case of an invalid UPD frame that has a very high UDP length value (e.g. >32k), this checksum calculation takes about 2.5ms. During that time other tasks running with a lower priority are blocked. In most cases this functions is called in the context of the HAL-EDD component, which interfaces to the HAL of the XC. This context usually has a very high priority in the sytem.
However, the function DrvEddReceiveCbk() should be optimized so that invalid frames will be rejected efficiently.
