| 129 | * DOC: packet coalesce support | ||
| 130 | * | ||
| 131 | * In most cases, host that receives IPv4 and IPv6 multicast/broadcast | ||
| 132 | * packets does not do anything with these packets. Therefore the | ||
| 133 | * reception of these unwanted packets causes unnecessary processing | ||
| 134 | * and power consumption. | ||
| 135 | * | ||
| 136 | * Packet coalesce feature helps to reduce number of received interrupts | ||
| 137 | * to host by buffering these packets in firmware/hardware for some | ||
| 138 | * predefined time. Received interrupt will be generated when one of the | ||
| 139 | * following events occur. | ||
| 140 | * a) Expiration of hardware timer whose expiration time is set to maximum | ||
| 141 | * coalescing delay of matching coalesce rule. | ||
| 142 | * b) Coalescing buffer in hardware reaches it's limit. | ||
| 143 | * c) Packet doesn't match any of the configured coalesce rules. | ||
| 144 | * | ||
| 145 | * User needs to configure following parameters for creating a coalesce | ||
| 146 | * rule. | ||
| 147 | * a) Maximum coalescing delay | ||
| 148 | * b) List of packet patterns which needs to be matched | ||
| 149 | * c) Condition for coalescence. pattern 'match' or 'no match' | ||
| 150 | * Multiple such rules can be created. | ||
