22cd0d47fa This commit attempts remove some long standard confusion in naming and some actual problems that result from the naming confusion. The basic problem is the standard MTU does not include the size of the Ethernet header. For clarity, I changed the naming of most things called MTU to PKTSIZE. For example, CONFIG_NET_ETH_MTU is now CONFIG_NET_ETH_PKTSIZE.
This makes the user interface a little hostile.  People thing of an MTU of 1500 bytes, but the corresponding packet is really 1514 bytes (including the 14 byte Ethernet header).  A more friendly solution would configure the MTU (as before), but then derive the packet buffer size by adding the MAC header length.  Instead, we define the packet buffer size then derive the MTU.

The MTU is not common currency in networking.  On the wire, the only real issue is the MSS which is derived from MTU by subtracting the IP header and TCP header sizes (for the case of TCP).  Now it is derived for the PKTSIZE by subtracting the IP header, the TCP header, and the MAC header sizes.  So we should be all good and without the recurring 14 byte error in MTU's and MSS's.

Squashed commit of the following:

    Trivial update to fix some spacing issues.
    net/: Rename several macros containing _MTU to _PKTSIZE.
    net/: Rename CONFIG_NET_SLIP_MTU to CONFIG_NET_SLIP_PKTSIZE and similarly for CONFIG_NET_TUN_MTU.  These are not the MTU which does not include the size of the link layer header.  These are the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename CONFIG_NET_6LOWPAN_MTU to CONFIG_NET_6LOWPAN_PKTSIZE and similarly for CONFIG_NET_TUN_MTU.  These are not the MTU which does not include the size of the link layer header.  These are the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename CONFIG_NET_ETH_MTU to CONFIG_NET_ETH_PKTSIZE.  This is not the MTU which does not include the size of the link layer header.  This is the full size of the packet buffer memory (minus any GUARD bytes).
    net/: Rename the file d_mtu in the network driver structure to d_pktsize.  That value saved there is not the MTU.  The packetsize is the memory large enough to hold the maximum packet PLUS the size of the link layer header.  The MTU does not include the link layer header.

e59b26370d Squashed commit of the following:
Fix a few typo/compilation problems.
    net/:  Remove all CONFIG_NET_xxx_TCP_RECVWNDO configuration variables.  They were used only to initialize the d_recwndo of the network device structure which no longer exists.
    net/:  Remove the device TCP receive window field (d_recvwndo) from the device structure.  That value is no longer retained, but is calculated dynamically.
    Remove some dangling references to CONFIG_NET_TCP_RWND_CONTROL.
    net/tcp:  Take read-ahead throttling into account when calculating the TCP receive window size.
    net/tcp: tcp_get_recvwindow() now returns the receive window size directly (vs. indirectly via the device structure).
    net/tcp:  Remove CONFIG_NET_TCP_RWND_CONTROL.  TCP window algorithm is now trigged only by CONFIG_NET_TCP_READAHEAD.

6a6bf1b62f :Remove CONFIG_NET_6LOWPAN_FRAMELEN. In this case where multiple radios are support3d, this may not be a constant. 6LoWPAN now always queries the driver to get the maximum frame length. 2017-09-10 11:40:54 -06:00

c217c663ae 6LoWPAN: Remove the option to disable fragmentation support. Two reasons: (1) First fragementation is always required becaues IPv6 requires an MTU of 1280 bytes. The is no application use case that can work without fragmentation support. And (2) it greatly reduces the complexity of the code. 2017-09-10 10:49:27 -06:00

88a87f8e3f 6LoWPAN: The original, Contiki-based design used only a single buffer for reassemblying larger packets. This could be a problem issue for hub configurations which really need the capability concurrently reassemble multiple incoming streams concurrently. These was also a design issue in that the reassembly buffer could be corrupted by outgoing packets. The design was extended to support multiple reassembly buffers, each associated with the reassembly tag and source address. This assures that there can be be no corruption of the reassembly once it has started. 2017-08-26 10:00:47 -06:00
