Hi, =0D In bge driver, we have BGE_JUMBO_FRAMELEN defined to 9018. if_bgereg.h:#define BGE_JUMBO_FRAMELEN 9018 =0D 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. =0D Any reason for allocating a hard coded 9018 size all Jumbo MTU frame (whether it is 9000 / 2000)? =0D Thanks, ~Siva The information contained in this electronic message and any attachments to= this message are intended for the exclusive use of the addressee(s) and= may contain proprietary, confidential or privileged information.
