2185456690 configs/: Update configurations for changes to apps/netutils/netinit configureation. MAC address configuration was represented by type long long. That is a problem for architectures that do not support typle long long. Replaces by two long configuration items. 2019-06-03 10:05:46 -06:00

16850297f3 libs/unistd and other affected files: Hostname support no longer depends on CONFIG_NET since the host name is also useful in the non-network environment. CONFIG_NET_HOSTNAME changed to CONFIG_LIB_HOSTNAME. 2019-01-27 06:56:16 -06:00

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.

70c59a9d91 This commit adds support for semi-standard IPPROTO_ICMP6 sockets. This is a replacement for the non-standard ICMPv6 ping support that violated the portable POSIX OS interface.
Squashed commit of the following:

    net/icmpv6: IPPROT_ICMP6 socket logic now builds without error.
    net/icmpv6:  Add support for read-ahead and poll(). Initial commit is just cloned from ICMP with the appropriate name changes.
    configs/:  All defconfig filess that include CONFIG_NET_ICMPv6_SOCKET=y need to select CONFIG_SYSTEM_PING6=y and deselect CONFIG_DISABLE_POLL.
    Update NSH documention to show that ping6 is now a built in command.
    net/icmpv6:  Add icmpv6_sendto.c and icmpv6_recvfrom.c.  Initial versions are just clones from icmp/ with appropriate name changes.
    net/icmpv6:  Clone some ICMP socket logic as the beginning of support for ICMPv6 socket support.
    Rename CONFIG_NET_ICMPv6_PING to CONFIG_NET_ICMPv6_SOCKET.  Move prototype for icmpv6_ping from include/nuttx/net/icmpv6 to net/icmpv6/icmpv6.h

09ab651e02 samv71-xult: Add support for the MRF24J40 radio and create a mrf24j40-starhub configuration. A few fixes to IPv6 and 6LoWPAN were required to have 6LoWPAN and Ethernet coexisting. Untested and expect some complexity in the bring-up. 2017-07-02 11:04:57 -06:00
