As per the following comment made in Linux driver.

/* The datasheet said that each descriptor can transfers up to 4096bytes
+ * But latter, a register documentation reduce that value to 2048
+ * Anyway using 2048 cause strange behaviours and even BSP driver use 2047
+ */

Can we keep CONFIG_ETH_BUFSIZE to 2044 ?

Thanks,
Amit.
