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
Sivakumar:
Allocations are done via the zone managers.. and thus setup
at kernel boot. A value like the MTU is set dynamically...
So doing something like this would be questionable IMO.. I
am sure it could be done.. but I don't see the value.
In theory you have a waste for just a short time.. before
its m_free'd
