Emery Hemingway	bbf7a6230e	VFS lwIP: restart DHCP with link-state changes ... Start and stop the DHCP state machine as the Nic link-state changes. Invoke the link state handler during configuration rather than assume that in the case of a downed link lwIP will defer DHCP until the link comes up. Additionally, support static DNS configuration via the "nameserver" configuration attribute. Fix #3388	2019-06-13 12:13:39 +02:00
Emery Hemingway	22ef3ed474	LwIP: manage Nic pbufs with a slab allocator ... LwIP skips a packet copy by wrapping Nic stream buffer regions in LwIP pbuf objects. Move from a fixed size array to a potentially unbounded slab allocator for managing this buffer metadata. Ref #2335	2018-08-28 16:45:23 +02:00
Emery Hemingway	d9a4773194	LwIP VFS plugin ... This patch reintroduces the LwIP stack to libc as a VFS plugin implementing the socket_fs interface. Rather than use LwIP's socket emulation layer this plugin interfaces directly to LwIP raw API and is single threaded. The internal TCP parameters of the stack are untuned.
