In most cases, host that receives IPv4 and IPv6 multicast/broadcast packets does not do anything with these packets. Therefore the reception of these unwanted packets causes unnecessary processing and power consumption. Packet coalesce feature helps to reduce number of received interrupts to host by buffering these packets in firmware/hardware for some predefined time. Received interrupt will be generated when one of the following events occur. a) Expiration of hardware timer whose expiration time is set to maximum coalescing delay of matching coalesce rule. b) Coalescing buffer in hardware reaches it's limit. c) Packet doesn't match any of the configured coalesce rules. This patch adds set/get configuration support for packet coalesce. User needs to configure following parameters for creating a coalesce rule. a) Maximum coalescing delay b) List of packet patterns which needs to be matched c) Condition for coalescence. pattern 'match' or 'no match' Multiple such rules can be created. This feature needs to be advertised during driver initialization. Drivers are supposed to do required firmware/hardware settings based on user configuration.
