The private data section of ndis_packets has a 'packet flags' byte
which has two important flags in it: the 'allocated by NDIS' flag
and the 'media specific info present' flag. There are two Windows macros
for getting/setting media specific info fields within the ndis_packet
structure which can behave improperly if these flags are not initialized
correctly when a packet is allocated. It seems the correct thing
to do is always set the NDIS_PACKET_ALLOCATED_BY_NDIS flag on
all newly allocated packets.
This fixes the crashes with the Intel Centrino wireless driver.
My sample card now seems to work correctly.
Also, fix a potential LOR involving ndis_txeof() in if_ndis.c.
