Regarding Jumbo frame implementation in bge

[sivakumar.subramani at wipro.com]

Hi,

In bge driver, we have BGE_JUMBO_FRAMELEN defined to 9018.
if_bgereg.h:#define BGE_JUMBO_FRAMELEN  9018

This macro is used to allocate the memory for jumbo buffer. If I have a
MTU size of 2000, still bge will allocate the jumbo buffer of size
BGE_JUMBO_FRAMELEN. Instead can we make the size to be depend on the
MTU. I mean instead of using BGE_JUMBO_FRAMELEN macro we can use MTU +
IP header + CRC for Jumbo buffer size.

Any reason for allocating a hard coded 9018 size all Jumbo MTU frame
(whether it is 9000 / 2000)?

Thanks,
~Siva
