/*Defines for minimal and maximal RX buffer size. This size includes the spi 
  header and hci header.
  The maximal buffer size derives from:
    MTU + HCI header + SPI header + sendto() agrs size
  The minimum buffer size derives from:
    HCI header + SPI header + max args size

  This buffer is used for receiving events and data.
  The packet can not be longer than MTU size and CC3000 does not support 
  fragmentation. Note that the same buffer is used for reception of the data 
  and events from CC3000. That is why the minimum is defined. 
  The calculation for the actual size of buffer for reception is:
  Given the maximal data size MAX_DATA that is expected to be received by
  application, the required buffer is:
  Using recv() or recvfrom():
 
    max(CC3000_MINIMAL_RX_SIZE, MAX_DATA + HEADERS_SIZE_DATA + fromlen
    + ucArgsize + 1)
 
  Using gethostbyname() with minimal buffer size will limit the host name
  returned to 99 bytes only.
  The 1 is used for the overrun detection 

  Buffer size increased to 130 following the add_profile() with WEP security
  which requires TX buffer size of 130 bytes: 
  HEADERS_SIZE_EVNT + WLAN_ADD_PROFILE_WEP_PARAM_LEN + MAX SSID LEN + 4 * MAX KEY LEN = 130
  MAX SSID LEN = 32 
  MAX SSID LEN = 13 (with add_profile only ascii key setting is supported, 
  therfore maximum key size is 13)
