264a5a3e97 Rename IP and Ethernet equality checkers from _cmp to _eq 
Functions ending in cmp are expected to return 0 on equality but these
return non-zero.

eth_addr_cmp -> eth_addr_eq

ip_addr_cmp -> ip_addr_eq
ip4_addr_cmp -> ip4_addr_eq
ip6_addr_cmp -> ip6_addr_eq

ip_addr_netcmp -> ip_addr_net_eq
ip4_addr_netcmp -> ip4_addr_net_eq
ip6_addr_netcmp -> ip6_addr_net_eq

ip_addr_cmp_zoneless -> ip_addr_zoneless_eq
ip6_addr_cmp_zoneless -> ip6_addr_zoneless_eq

ip6_addr_cmp_zone -> ip6_addr_zone_eq
ip6_addr_netcmp_zoneless -> ip6_addr_net_zoneless_eq
ip6_addr_nethostcmp -> ip6_addr_nethost_eq
ip6_addr_cmp_packed -> ip6_addr_packed_eq
ip6_addr_cmp_solicitednode -> ip6_addr_solicitednode_eq

All call sites have been changed, and fallback macros have been added to not
break external users.

40a563cdd3 dns: Use dns_backupserver_available() instead of open-coded 
Slightly better readability by calling dns_backupserver_available()
instead of open-coded. Also move dns_backupserver_available() function
up to avoid forward declaration.

26771d0800 Add @todo: scope ip6addr? 2017-07-18 19:17:17 +02:00
Our Air Quality
5eff45cac0 Correct a few uses of sizeof(ip6_addr_t) to sizeof(ip6_addr_p_t) 
The ip6_addr_t structure may have an addition slot so is not necessarily
the size of an ipv6 address, so some uses of sizeof(ip6_addr_t) were not
correct.

be7ae5e36b dns: Slightly improve dns_alloc_random_port implementation 
Having the variable namining ret for a pointer makes the code looks odd,
ret looks like a value variable. Rename ret to pcb.
Also simplify the code in the do {} while() loop.

13fb616bb2 Cleanup hton*/ntoh* function handling and platform abstraction 
Let lwip use functions/macros prefixed by lwip_ internally to avoid naming clashes with external #includes.
Remove over-complicated #define handling in def.h
Make functions easier to override in cc.h. The following is sufficient now (no more LWIP_PLATFORM_BYTESWAP):
#define lwip_htons(x) <your_htons>
#define lwip_htonl(x) <your_htonl>
