I have board MCB2300 (with LPC 2378 microprocessor). I read in LPC23xx User manual that MAXIMUM FRAME LENGTH (MAXF)sets to the value 0x0600, which represents a maximum receive frame of 1536 octets. This way, max. outgoing TCP data size should be less than (1536 - ETH_HEADER_SIZE - IP_HEADER_SIZE - TCP_HEADER_SIZE). The result is 1536-14-20-20 = 1482 bytes. Is it possible to transmit more than 1536 bytes via ethernet once only?
