7af358ed93 esp_eth: Fix w5500 to break from potentially infinite tx loop 
The issue typically happens for link-down during Tx. Added two retry levels, one before checking the sanity of the w5500 phy register and another for the Tx done itself (if the device is in the sane state)

dfe9580967 esp_eth: Fix w5500 to correctly read registers on -Os 
Reading SPI data may come in 4-byte units and thus result in unwanted
overwrites if smaller size registers read, especially if multiple placed
one after another. Fixed by using direct reads to `trans` structure for
sizes smaller or equal to 4.

1e905acacf eth: support W5500 MAC RAW mode 
W5500 features an Ethernet MAC+PHY, plus a HW SOCKET implementation.
But in IDF, we only use software TCP/IP stack, which means we have
to bypass the HW TCP/IP stack in W5500.
So we enables the MAC RAW mode in W5500.
