[PATCH iwl-net 0/2] ice: fix AQ command 0x06EE usage by retrying

[Dawid Osuchowski <dawid.osuchowski@linux.intel.com>]

The Admin Queue (AQ) command 0x06EE can return EBUSY when firmware link
management holds the i2c bus used to communicate with the module.

According to Intel(R) Ethernet Controller E810 Datasheet Rev 2.8 [1]
Section 3.3.10.4 Read/Write SFF EEPROM (0x06EE)
request should be retried upon receiving EBUSY from firmware.

Instead of relying on the caller of ice_aq_sff_eeprom() to implement
retrying, use the existing retry infrastructure in ice_sq_send_cmd_retry()
to always attempt retry on receiving EBUSY.

Reproduction steps
------------------
	# ethtool -m <interface_name>
	netlink error: Input/output error
