Bits 31:0 – NFRX[31:0]: 1519 to Maximum Byte Frames Received without Error

1519 to Maximum Byte Frames Received without Error

This bit field counts the number of 1519 Byte or above frames successfully received without error. Maximum frame size is determined by the Maximum Frame Size bit (MAXFS, 1536 Bytes) or Jumbo Frame Size bit (JFRAME, 10240 Bytes) in the Network Configuration Register (GMAC_NCFGR). Excludes pause frames, and is only incremented if the frame is successfully filtered and copied to memory.
