Before initializing the chip's engine, driver currently closes a set of registers on the HW's ingress flow to prevent packets from slipping in while they're not supposed to. This configuration is insufficient, as there are some scenarios where packets would still arrive even when said registers are set, but the management firmware already closes other per-port registers that do suffice, making this setting unnecessray.

由 Rahul Verma 提交于
In order to access HW registers driver needs to acquire a PTT entry [mapping between bar memory and internal chip address]. Since acquiring PTT entries could fail [at least in theory] as their number is finite and other flows can hold them, we reserve special PTT entries for 'important' enough flows - ones we want to guarantee that would not be susceptible to such issues. One such special entry is the 'main' PTT which is meant to be used in flows such as chip initialization and de-initialization. However, there are other flows that are also using that same entry for their own purpose, and might run concurrently with the original flows [notice that for most cases using the main-ptt by mistake, such a race is still impossible, at least today]. This patch re-organizes the various functions that currently use the main_ptt in one of two ways: - If a function shouldn't use the main_ptt it starts acquiring and releasing it's own PTT entry and use it instead. Notice if those functions previously couldn't fail, they now can [as acquisition might fail]. - Change the prototypes so that the main_ptt would be received as a parameter [instead of explicitly accessing it]. This prevents the future risk of adding codes that introduces new use-cases for flows using the main_ptt, ones that might be in race with the actual 'main' flows.

When qedr is enabled, qed would try dividing the msi-x vectors between L2 and RoCE, starting with L2 and providing it with sufficient vectors for its queues. Problem is qed would also do that for storage partitions, and as those don't need queues it would lead qed to award those partitions with 0 msi-x vectors, causing them to believe theye're using INTa and preventing them from operating.
