107 The following shows what the header and subheader looks like for NS_LS_DRIVER
108 The capture was taken on HPUX11 and for a 100baseT interface.
110 000080 00 44 00 0b 00 00 00 02 00 00 00 00 20 00 00 00
111 000090 00 00 00 00 00 00 04 06 00 00 00 00 00 00 00 00
112 0000a0 00 00 00 74 00 00 00 74 3c e3 76 19 00 06 34 63
113 0000b0 ff ff ff ff 00 00 00 00 00 00 00 00 ff ff ff ff
114 0000c0 00 00 00 00 00 00 01 02 00 5c 00 5c ff ff ff ff
115 0000d0 3c e3 76 19 00 06 34 5a 00 0b 00 14 <here starts the MAC header>
117 Each entry starts with 0x0044000b
119 The values 0x005c at position 0x0000c8 and 0x0000ca matches the number of
120 bytes in the packet up to the next entry, which starts with 0x00440b again.
121 These are the captured and real and captured length of the packet.
123 The values 0x00000074 at positions 0x0000a0 and 0x0000a4 seems to indicate
124 the same number as positions 0x0000c8 and 0x0000ca but added with 24.
125 Perhaps we have here two layers of headers.
126 The first layer is fixed and consists of all the bytes from 0x000084 up to and
127 including 0x0000c3 which is a generic header for all packets captured from any
128 device. This header might be of fixed size 64 bytes (although the first two
129 bytes appear to be the length of that header, in big-endian format) and there
130 might be something in it which indicates the type of the next header which is
131 link type specific. Following this header there is another header for the
132 100baseT interface which in this case is 24 bytes long spanning positions
133 0x0000c4 to 0x0000db.
135 In another capture, claimed to be taken on an HP-UX 8 box, but with a
136 file header suggesting it was taken on HP-UX 10.20, the header for
137 NS_LS_DRIVER looks like:
139 000080 00 40 00 0b ff ff ff ff 00 00 00 00 00 00 00 00
140 000090 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
141 0000a0 00 00 00 51 00 00 00 51 42 02 5e bf 00 0e ab 7c
142 0000b0 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00
143 0000c0 00 02 01 00 00 3b 00 3b ff ff ff ff 42 02 5e bf
144 0000d0 00 0e 8e 44 00 0b <here starts the MAC header>
146 When someone reports that the loading of the captures breaks, we can
147 compare this header above with what he/she got to learn how to
148 distinguish between different types of link specific headers.
151 For now, the subheader for 100baseT seems to be
159 struct nettlrec_ns_ls_drv_eth_hdr {
170 * This is the size of an NS_LS_DRV_ETH header; it is *not* necessarily
