Probably my question is stupid, I'm not a guru in the FreeBSD programming but anyway. I see in the FreeBSD net drivers send packet procedures that those procedures operates with the pointer to the mbuf structure to get a packet to send. I see that this structure consists of [some] fragments linked in a chain. So the question is: Are these fragments suitable in size for pushing into the card which requires the frame to be splitted into 802.11 compliant fragments (they should be less than 1500 bytes w/o headers and CRC)? Or I should glue those fragments together and then re-split them into appropriate pieces? (The card is registered as ethernet and so on) Thank you in advance, Alexey Morozov To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-mobile" in the body of the message
