From: Przemyslaw Patynowski <przemyslawx.patynowski@xxxxxxxxx>
[ Upstream commit 4635fd3a9d77581498f34ab9a7e4bcc211bf0a4c ]
Remove from supported_coalesce_params ETHTOOL_COALESCE_MAX_FRAMES
and ETHTOOL_COALESCE_MAX_FRAMES_IRQ. As tx-frames-irq allowed
user to change budget for iavf_clean_tx_irq, remove work_limit
and use define for budget.
Without this patch there would be possibility to change rx/tx-frames
and rx/tx-frames-irq, which for rx/tx-frames did nothing, while for
rx/tx-frames-irq it changed rx/tx-frames and only changed budget
for cleaning NAPI poll.
Fixes: fbb7ddfef253 ("i40evf: core ethtool functionality")
