Add a network keep alive packet
Keep alive functionality enables the WLAN chip to automatically send an arbitrary IP packet and/or 802.11 Null Function data frame at a regular interval
This feature may be used to maintain connectivity with a Wi-Fi AP and/or remote network application
A maximum of 4 keep alive packets can be configured to operate concurrently Keep alive packet functionality only works with client (STA) mode If the keep alive packet length is set to 0, a Null-Function Data frame is automatically used as the keep alive Any ethernet packet can be sent as a keep alive packet
| [in] | keep_alive_packet_info | : Pointer to a wiced_keep_alive_packet_t structure used to setup the keep alive packet |

Disable a keep alive packet specified by id
| [in] | id | : ID of the keep alive packet to be disabled |

Get information about a keep alive packet
The ID of the keep alive packet should be provided in the keep_alive_info structure The application must pre-allocate a buffer to store the keep alive packet that is read from the WLAN chip The length of the buffer must be provided in the packet_length field of the structure The repeat period and keep alive packet bytes are populated by this function upon successful return
